Baseball Statistics
ERA, FIP, WHIP, OBP, Batting Average & Magic Number
ERA stands for Earned Run Average. It measures the average number of earned runs a pitcher allows per nine innings pitched. It is one of the oldest and most widely used statistics in baseball. The formula is: ERA = (Earned Runs × 9) ÷ Innings Pitched. An ERA below 3.00 is considered excellent in MLB; below 2.00 is elite. ERA has been an official MLB statistic since 1913.
FIP (Fielding Independent Pitching) measures pitching performance using only outcomes the pitcher directly controls: strikeouts, walks, hit-by-pitches, and home runs. Unlike ERA, FIP removes the influence of team defense and batted ball luck. Research shows FIP is a more accurate predictor of a pitcher's future ERA than their current ERA, because ERA can be inflated or deflated by fielding quality. A FIP below 3.00 is elite.
WHIP stands for Walks plus Hits per Inning Pitched. It measures the average number of baserunners a pitcher allows per inning. The formula is: WHIP = (Walks + Hits) ÷ Innings Pitched. A WHIP below 1.00 is excellent — meaning the pitcher allows fewer than one baserunner per inning on average. Pedro Martinez holds the all-time single-season record with a 0.737 WHIP in 2000.
OBP = (Hits + Walks + Hit By Pitch) ÷ (At Bats + Walks + Hit By Pitch + Sacrifice Flies). OBP measures how often a batter reaches base per plate appearance and is considered more valuable than batting average because it includes walks. An OBP above .370 is excellent. Ted Williams holds the single-season record with a .553 OBP in 1941.
Batting Average = Hits ÷ At Bats. A batting average of .300 is considered excellent in MLB — meaning the batter gets a hit 30% of the time. Walks are not counted as at-bats and do not affect batting average. Ty Cobb holds the all-time MLB career batting average record at .366. In cricket, batting average is calculated differently: Total Runs ÷ Number of Times Dismissed.
The magic number is the combined total of wins by the leading team and losses by the closest rival needed to clinch a playoff spot or division title. Formula: Magic Number = 163 − (Your Wins + Rival Losses). When the magic number reaches zero, your team has officially clinched. The 163 accounts for the 162-game season plus one potential tiebreaker.
Basketball & Dunk
Game Score and vertical jump calculations
Game Score was developed by ESPN analyst John Hollinger to summarize a player's complete single-game performance in one number. Formula: GmSc = Points + 0.4×FG − 0.7×FGA − 0.4×FTA + 0.7×ORB + 0.3×DRB + STL + 0.7×AST + 0.7×BLK − TO − 0.4×PF. A Game Score of 10 is average for NBA starters, 20–30 is strong, and 40+ is historic. Michael Jordan holds the record at 64.6.
To dunk, your hand must clear the 10-foot rim by at least 6 inches — meaning you need a reach of at least 10 feet 6 inches (126 inches) above the floor. For a 6-foot player with a typical standing reach of 94–96 inches, this requires a vertical jump of roughly 28–33 inches. The exact requirement depends on your standing reach, hand size, and dunking technique.
Standing reach is approximately 1.33 times your height. A 6-foot (72-inch) person typically has a standing reach of around 95–96 inches (about 8 feet). You can measure it precisely by standing flat-footed against a wall and reaching up as high as possible with your dominant hand, then measuring the height.
The most effective vertical jump training combines plyometrics and strength training. Key exercises include: box jumps, depth jumps, Bulgarian split squats, single-leg Romanian deadlifts, and sprint intervals. Most athletes can gain 6–12 inches of vertical jump within 6–12 months of consistent, focused training. The most important factor is progressive overload — gradually increasing workout intensity over time.
Fitness & Calorie Calculators
Hiking, stairs, sauna, and burpee calorie burn
A typical moderate hike burns 400–700 calories per hour depending on body weight, elevation, terrain difficulty, and pack weight. A 10 km hike with 800 meters of elevation gain burns approximately 1,200–1,800 calories for an average adult. Our hiking calorie calculator factors in flat distance, uphill gain, downhill terrain, body weight, and backpack load for a comprehensive estimate.
MET stands for Metabolic Equivalent of Task. A MET of 1.0 equals your resting metabolic rate (sitting quietly). Activities are assigned MET values based on how much more energy they require than rest. The calorie formula is: Calories = MET × Weight (kg) × Time (hours). For example, vigorous stair climbing has a MET of 8.0–9.0, meaning it burns 8–9 times more energy than sitting still.
At moderate-to-vigorous intensity, burpees burn approximately 10–14 calories per minute for a 70 kg (154 lb) person — making them one of the most calorie-efficient bodyweight exercises available. 100 burpees burns roughly 50–100 calories depending on pace and body weight. The afterburn effect (EPOC) also keeps your metabolism elevated for 15–30 minutes after the workout.
Yes, but modestly. Your body burns extra calories in a sauna to maintain core temperature in the high-heat environment. A 15–20 minute sauna session typically burns 100–200 calories for an average adult. However, the immediate weight loss you see on the scale is mostly water weight from sweating, which returns when you rehydrate. The real benefits of regular sauna use are improved cardiovascular health, muscle recovery, and stress reduction.
A 70 kg person burns approximately 50–100 calories per 10 minutes of stair climbing depending on intensity. Vigorous stair climbing burns around 8–10 calories per minute — comparable to a light jog but much easier on impact equipment. Three 10-minute stair sessions per day can contribute 150–200 extra calories burned, making it one of the most accessible daily fitness habits.
A heavier pack significantly increases calorie burn because your muscles must work harder to carry the additional weight. A 5 kg (11 lb) daypack adds approximately 7% more calories burned. A 20 kg (44 lb) expedition pack can increase total energy expenditure by 25–30% compared to hiking without a pack. Our hiking calorie calculator accounts for pack weight in its estimate.
Hiking Time & Planning
Trail time estimation and outdoor planning
Naismith's Rule is the gold standard formula for hiking time estimation, developed by Scottish mountaineer William Naismith in 1892. The rule states: allow 1 hour for every 5 km of horizontal distance, plus 1 additional hour for every 600 meters of elevation gain. For example, a 10 km hike with 600 m of elevation would take approximately 3 hours (2 hours for distance + 1 hour for elevation). It remains widely used by hikers, trail organizations, and military planners worldwide.
The calculator gives an excellent baseline estimate for fit adults with light packs on clear trails. Add 10–30% buffer time for rest breaks, photography stops, challenging terrain, or group hiking with varying fitness levels. Weather, trail surface quality, altitude, and fatigue also affect your actual pace. Always plan conservatively — it's better to finish early than to be caught on the trail after dark.
Use 5 km/h as your default pace for a fit adult on a clear trail with a light daypack. Adjust down to 3–4 km/h if you are: carrying a heavy backpack (15+ kg), hiking with children or elderly companions, traversing rough or technical terrain, hiking at high altitude (above 3,000 m), or if you are a beginner hiker. The calculator lets you enter a custom pace so you can use your personal known trail pace.
Elevation gain has a major impact on hiking time. Per Naismith's Rule, every 600 meters of elevation gain adds one full hour to your hike, regardless of horizontal distance. A 5 km flat hike takes about 1 hour, but a 5 km hike with 1,200 m of elevation gain takes approximately 3 hours — three times as long. This is why mountain trails always feel much harder than their horizontal distance suggests.
Education & CGPA
GPA, CGPA, and academic performance calculations
GPA (Grade Point Average) is calculated for a single semester — it reflects your performance in that term only. CGPA (Cumulative Grade Point Average) is calculated across all completed semesters and reflects your overall academic performance throughout your degree. Universities, employers, and scholarship committees almost always use CGPA, not semester GPA, to evaluate academic achievement.
CGPA = Total Grade Points ÷ Total Credit Hours, where Total Grade Points = sum of (Grade Point × Credit Hours) for every subject across all semesters. The key is credit-weighting — a 4-credit course has twice the impact of a 2-credit course. The most common mistake is averaging individual semester GPAs instead of recalculating from all subjects, which gives incorrect results when semesters have different total credit loads.
The conversion method varies by institution. Common approaches include: multiplying CGPA by 9.5 (used by many Indian universities including Anna University), multiplying by 25 (some Pakistani and international systems), or using a custom grade table provided by your university. Always confirm your institution's official conversion method before using any result in an application, as different systems produce different numbers.
Most competitive graduate programs require a minimum CGPA of 3.0 on a 4.0 scale (equivalent to a B average). Highly competitive programs typically prefer 3.5 or above. For top-tier universities, research positions, and merit scholarships, a CGPA of 3.7 or higher significantly strengthens your application. However, strong GRE/GMAT scores, research experience, and letters of recommendation can partially compensate for a lower CGPA.
To calculate your true cumulative CGPA correctly, the calculator needs to know your existing academic record so it can combine it with your new semester grades. If you only enter the new semester without your previous history, you'd get only your semester GPA, not your cumulative GPA. The calculation is: New CGPA = (Previous CGPA × Previous Credits + New Grade Points) ÷ (Previous Credits + New Credits).
