What is the Calorie Burn Calculator?
A 30-minute jog burns a very different number of calories for a 120-pound runner than for a 220-pound one. This calculator bridges that gap with METs — metabolic equivalents — the standard way exercise scientists rate activity intensity. One MET is the energy you burn sitting still. Walking at a brisk pace rates about 3.5 METs, cycling moderately about 6 to 10, and running anywhere from 7 to 12 depending on speed. The formula multiplies your MET value by your weight in kilograms and the duration in hours.
Picture a 170-pound teacher in Portland who jogs for 30 minutes at a 7-MET pace. That works out to roughly 270 calories — about the same as a glazed donut from the shop on her route home. The same jog for her 220-pound running partner burns closer to 350. The calculator also shows calories per minute and per hour, handy for comparing a 20-minute HIIT session against an hour-long walk.
MET tables describe averages, not your body specifically. Fitness level, terrain, temperature, and how hard you are really pushing all move the true number. Use the result to compare workouts and plan weekly activity, not as a precise bank balance of calories.
With the pre-filled defaults — Body Weight (kg) 70, MET Value 7, Duration (minutes) 30 — the Calorie Burn Calculator returns Calories Burned (kcal) 245, Calories per Minute 8.17, Calories per Hour 490. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
How to Use the Calorie Burn Calculator
- 1Type your weight in the Body Weight (kg) field — 170 lbs is about 77 kg.
- 2Enter the intensity in the MET Value box: 3.5 for brisk walking, 7 for jogging, 10 for hard cycling.
- 3Type how long you exercised in the Duration (minutes) field, for example 30.
- 4Read Calories Burned (kcal) for the session total.
- 5Compare Calories per Minute and Calories per Hour across different activities to find the best bang for your time.

Common Examples
| Scenario | Calculation | Result |
|---|---|---|
| 70kg jogging 30 min | Body Weight (kg) = 70, MET Value = 7, Duration (minutes) = 30 | Calories Burned (kcal) = 245; Calories per Minute = 8.17; Calories per Hour = 490 |
| 80kg cycling 45 min | Body Weight (kg) = 80, MET Value = 8, Duration (minutes) = 45 | Calories Burned (kcal) = 480; Calories per Minute = 10.67; Calories per Hour = 640 |

Calculation Progression Roadmap
How the Calorie Burn Calculator turns your inputs into a result, step by step — from the values you type to the answer you read.
Gather your inputs
Type in your Body Weight (kg), MET Value, and Duration (minutes). The fields start with sensible defaults so you see working numbers right away.
Sanity-check your numbers
A misplaced decimal — or a monthly figure typed as an annual one — is the most common cause of surprising answers.
The math runs itself
The calculator evaluates MET Value × Body Weight (kg) × Duration (minutes) ÷ 60 on every keystroke — there is no submit button to press.
Read your results
Your Calories Burned (kcal), Calories per Minute, and Calories per Hour appear instantly. With the pre-filled defaults, that is Calories Burned (kcal) 245, Calories per Minute 8.17, Calories per Hour 490. Change any input to see the effect immediately.
Test a what-if
Try a bigger and a smaller value for one input. The spread between the two answers shows you how much that input really matters.
Real-World Examples
Fresh scenarios — starting with morning routine check — worked through with different numbers than the examples above, so you can watch the formula handle new situations.
Morning routine check
For Body Weight (kg) 140, MET Value 7, Duration (minutes) 30, expect Calories Burned (kcal) 490, Calories per Minute 16.33, Calories per Hour 980.
Fitness tracking
A quick run with Body Weight (kg) 35, MET Value 7, Duration (minutes) 30 gives Calories Burned (kcal) 123, Calories per Minute 4.08, Calories per Hour 245.
Preparing for a checkup
With Body Weight (kg) 105, MET Value 7, Duration (minutes) 30, the calculator returns Calories Burned (kcal) 368, Calories per Minute 12.25, Calories per Hour 735.
