是什么 Calories Burned Calculator?

▾

A calories burned calculator estimates energy expenditure during physical activity using MET (Metabolic Equivalent of Task) values multiplied by body weight and duration.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

公式

▾

f(x)Calories per minute = MET × weight(kg) × 3.5 / 200; Total = Calories/min × duration(minutes)

变量说明

W	Body weight	kg	—
T	Duration	minutes	—

如何 Calories Burned Calculator

▾

1Calories/min = MET × weight (kg) × 3.5 / 200
2Total = Calories/min × duration (minutes)
3MET 1 = sitting at rest; running is MET 8–12
4Actual calorie burn varies with fitness level and intensity

例题解析

▾

示例 1

已知:Running (MET 8), 70kg, 30 minutes

结果:8 × 70 × 3.5 / 200 × 30 = 294 calories

MET Values for Common Activities

▾

Activity	MET value	Calories/hr (70kg)
Sleeping	0.9	63
Walking (5km/h)	3.5	245
Cycling (moderate)	8.0	560
Running (10km/h)	10.0	700
Swimming (laps)	8.0	560
HIIT	12.0	840

常见问题

▾

What is MET?

MET = metabolic equivalent. 1 MET = sitting at rest. Running is 8-12 MET depending on speed.

Why does body weight matter?

Heavier bodies require more energy to move. A 90kg person burns more calories than 70kg doing the same activity.

Are these estimates accurate?

Within ±10-20%. Actual burn varies by fitness level, age, gender, and heart rate. Wearables use personal data.
