Calories Burned Calculator

Calories Burned Calculator

How to Use the Calculator

Using this tool is simple:

1. Select your activity (e.g., running, cycling, yoga, walking).
2. Enter your body weight (in kilograms or pounds).
3. Enter the duration of your activity (in minutes).
4. Click Calculate to see the estimated calories burned.

Introduction:

Have you ever finished a workout or even a long day of chores and wondered “How many calories did I just burn?” While smartwatches and apps try to give estimates, they are often inconsistent. That’s where this calculator comes in—it gives you a quick, research-based estimate of calories burned for hundreds of daily activities and exercises.

Because every body is unique, the result is only an estimate, but it shows how your weight, workout time, and activity intensity affect your calorie expenditure. Whether your goal is weight loss, maintenance, or muscle gain, knowing how many calories you burn is an important step.

Factors That Affect Calories Burned:

1. Body Weight and Duration

• A heavier person burns more calories, even at rest.
• Longer workouts burn more calories, but the intensity of the exercise makes the biggest difference.

2. Exercise Intensity

Higher intensity = more calories burned.

For example:

• Walking slowly → around 2 MET (light effort)
• Playing doubles tennis → around 5 MET (moderate effort)
• Jumping rope fast → around 11 MET (vigorous effort)

3. Other Factors

• Age – older people burn fewer calories due to lower muscle mass.
• Body composition – more muscle means higher calorie burn.
• Fitness level – fitter people use energy more efficiently.
• Temperature – slightly higher burn in hot environments.
• Diet and sleep – poor habits can slow metabolism.

How Calories Are Calculated:

This calculator uses a standard formula:

Calories burned = (Time in minutes × MET × Body weight in kg) ÷ 200

Example:

• Activity: Running at 8 MET
• Weight: 70 kg
• Duration: 30 minutes

Calories burned = (30 × 8 × 70) ÷ 200 = 840 calories

Accuracy of Results:

• MET values are averages based on a 70 kg (154 lb) healthy adult.
• Real calorie burn varies by age, muscle mass, health, and efficiency.
• Activities with frequent breaks (like tennis or basketball) may overestimate calorie burn.

While exact numbers require lab testing, this calculator gives a reliable everyday estimate and a good idea of workout intensity.

Final Note:

This calculator is more than just numbers—it’s a tool to help you understand your body better. Use it to plan workouts, track progress, and balance your calorie intake with activity for weight loss, muscle gain, or maintenance.
