# Calculator for the Heating Power of Humans

Calculates with how many watts a number of people heat. By burning food in their bodies, humans generate energy, which, among other things, is used to maintain their body temperature. This energy is released to the outside as heat. The more active a person is, the higher is this heating capacity. Clothing keeps the heat on people and thus reduces the heating output. The figures relate to adults of average height and are rough estimates.

### Heat output during activity

Sleep: 80W
Sedentary work: 120 watts
Light physical exertion: 200 watts
Heavy physical exertion: 500 watts

### Clothing factor

(Almost) no clothes: 1
Normal clothes: 2
Winter clothes: 3

 Number of people n: Heat output per person P: watts Clothing factor f: Total heating power Pg: watts

The formula for the calculation is: Pg = n * P / f

Example: 8 people with light summer clothing (f=1.5) in an office with mostly sedentary work but who have to get up and walk around frequently (P=140) heat with 747 watts.

Here you can convert metric units into customary and imperial units and convert temperature units.
