Calories Burned By Activity Calculator

Calories Burned Calculator Guidelines

You're just a few clicks away from actionable insights—here's how:

Using the Calculator Effectively

  • Select an Activity: Choose from the dropdown. Each option has a preset MET value.
  • Enter Duration: Specify how long you performed the activity in minutes.
  • Provide Your Weight: Input in kilograms or pounds (toggle if needed).
  • Click Calculate: The calculator uses scientific formulas to estimate calories burned.

Additional Tips

  • Use positive values for duration and weight only.
  • If you're switching between activities, calculate them separately and sum the totals.
  • Remember: these are estimates based on average population data.

Calories Burned Calculator Description

Understanding Calories Burned

Calories burned during physical activity are influenced by several core factors:

  • Type and intensity of activity
  • Duration of the activity
  • Your body weight

The Core Formula

To estimate calories burned, we use this well-established formula:

Calories Burned = MET × Weight (kg) × Duration (hours)

Where:

  • MET: Metabolic Equivalent of Task, a standardized value for each activity
  • Weight: Body weight in kilograms
  • Duration: Total activity time in hours

Reference MET Values

  • Walking (5 km/h): 3.5 METs
  • Running (9 km/h): 9.8 METs
  • Cycling (moderate): 8.0 METs

How to Use This Calculator

  1. Select the activity you performed.
  2. Enter the time spent (in minutes).
  3. Input your weight in kilograms or switch to pounds.
  4. Click "Calculate" to receive an estimated calorie burn based on MET science.

Real-World Mini Case Studies

Case Study 1: Jogging

Jane weighs 65 kg and jogs for 45 minutes. MET for jogging is 7.0.

Calories = 7.0 × 65 × (45 / 60) = 341.25 kcal

Case Study 2: Cycling

Mark weighs 80 kg and cycles at moderate effort for 90 minutes. MET is 8.0.

Calories = 8.0 × 80 × (90 / 60) = 960 kcal

Frequently Asked Questions

MET (Metabolic Equivalent of Task) quantifies the energy cost of physical activities. 1 MET is the energy expended at rest, and higher METs indicate more intense activity.

This calculator offers a general estimate using standardized MET values. Individual variations such as fitness level, metabolic rate, and external conditions can influence real results.

Fitness trackers use sensors and algorithms that may account for heart rate and movement, while this calculator uses a scientific estimation based on MET values and weight.

Yes. Muscle mass burns more energy than fat mass. Two people with the same weight but different compositions may burn different calories doing the same activity.

Use the closest matching activity based on intensity. You can also manually input the MET value if known.

Extended durations (e.g., 6+ hours) may result in overestimates as the body often adapts metabolically, lowering calorie burn efficiency over time.

Calorie burn will be minimal, and any error in MET assumptions can lead to disproportionately inaccurate results. Use caution for children or underweight individuals.

Activities like sprinting or competitive rowing have very high METs (12+). Ensure that the user is actually performing at that intensity; otherwise results may overestimate.

For sessions involving multiple activities, split the session into chunks and calculate each separately, then sum the results for accuracy.

Negative or zero values for weight or duration are invalid and will yield zero or undefined results. Always ensure positive inputs.

It depends on your weight and the activity's MET value. For example, a 70 kg person running (9.8 MET) for 1 hour burns about 686 calories.
