About the Calories Burned Calculator

Calories Burned is treated here as a quantitative relation between Body Weight, Duration and Activity and Calories Burned, Calories per Minute and MET Value Used.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
Calories = MET x Body Weight (kg) x Duration (hours)
For example: 75 kg person, running at 8.3 MET for 45 min:
= 8.3 x 75 x (45/60) = 467 kcal

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

Calories = MET x Body Weight (kg) x Duration (hours)
For example: 75 kg person, running at 8.3 MET for 45 min:
= 8.3 x 75 x (45/60) = 467 kcal

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Running 45 Minutes at 10 min/mile Pace

Inputs

weight_kg: 75 duration_min: 45 activity: 8.3
Calories Burned: 467 kcal. Calories per Minute: 10.4 kcal/min. MET Value Used: 8.3 METs

With Body Weight = 75, Duration = 45 and Activity = 8.3 as the stated inputs, the result is Calories Burned = 467 kcal, Calories per Minute = 10.4 kcal/min and MET Value Used = 8.3 METs. Each value corresponds to the declared output fields.

Example 2: Cycling 60 Minutes at Moderate Pace

Inputs

weight_kg: 80 duration_min: 60 activity: 6.8
Calories Burned: 544 kcal. Calories per Minute: 9.1 kcal/min. MET Value Used: 6.8 METs

With Body Weight = 80, Duration = 60 and Activity = 6.8 as the stated inputs, the result is Calories Burned = 544 kcal, Calories per Minute = 9.1 kcal/min and MET Value Used = 6.8 METs. Each value corresponds to the declared output fields.

Example 3: Swimming Laps 30 Minutes

Inputs

weight_kg: 70 duration_min: 30 activity: 9.8
Calories Burned: 343 kcal. Calories per Minute: 11.4 kcal/min. MET Value Used: 9.8 METs

With Body Weight = 70, Duration = 30 and Activity = 9.8 as the stated inputs, the result is Calories Burned = 343 kcal, Calories per Minute = 11.4 kcal/min and MET Value Used = 9.8 METs. Each value corresponds to the declared output fields.

Example 4: Walking 60 Minutes — Weight Loss Walk

Inputs

weight_kg: 90 duration_min: 60 activity: 3.8
Calories Burned: 342 kcal. Calories per Minute: 5.7 kcal/min. MET Value Used: 3.8 METs

With Body Weight = 90, Duration = 60 and Activity = 3.8 as the stated inputs, the result is Calories Burned = 342 kcal, Calories per Minute = 5.7 kcal/min and MET Value Used = 3.8 METs. Each value corresponds to the declared output fields.
