BTU per Second to Watts Calculator

Multiply BTU/s by about 1,055.06 to get watts.

BTU per second. Check the time unit: BTU/hr is 3,600 times smaller.

BTU/s
Cooling capacity

Enter a value in BTU/s to see it in cooling W.

BTU/s to watts formula

One International Table BTU is 1,055.05585262 joules, and 1 watt is 1 joule per second. So W = BTU/s × 1,055.05585262.

1 BTU/s equals 1,055.0559 cooling W.

1 × 3,600 = 3,600 BTU/hr; 3,600 × 0.2930710702 = 1,055.0559 cooling W

Check your time unit

1 BTU/s = 60 BTU/min = 3,600 BTU/hr. AC ratings use BTU/hr, so a BTU/s figure is usually from engineering or lab work.

A figure in plain BTU, with no time unit, is energy rather than a rate.
