How do you calculate calories burned lifting weights?

Here’s your equation: MET value multiplied by weight in kilograms tells you calories burned per hour (MET*weight in kg=calories/hour). If you only want to know how many calories you burned in a half hour, divide that number by two. If you want to know about 15 minutes, divide that number by four.
