BTU to kilowatt-hours formula

kWh = BTU ÷ 3412.141633

Take the value in BTU.
Divide it by 3412.141633 (the number of BTU in one kilowatt-hour).

Example: 10,000 BTU ÷ 3412.141633 = 2.93071 kWh.

Reverse formula (kilowatt-hours to BTU): BTU = kWh × 3412.141633. Example: 0.999958 kWh × 3412.141633 = 3,412 BTU.

Quick mental estimate: divide by about 3400. For exact answers use the converter above.

About BTU and kilowatt-hours

BTU (BTU). The British thermal unit (BTU, International Table) is about 1,055.06 joules: roughly the energy to heat one pound of water by 1 °F.

Kilowatt-hours (kWh). A kilowatt-hour is the energy used by a 1,000-watt device running for one hour, 3.6 million joules. Electricity bills are charged per kWh.

Frequently asked questions

How many kilowatt-hours in 1 BTU?

One BTU equals 0.000293071 kilowatt-hours. Looking at it the other way, one kilowatt-hour is 3,412.14 BTU.

How do you convert BTU to kilowatt-hours?

Divide the number of BTU by 3412.141633. For example, 10,000 BTU ÷ 3412.141633 = 2.93071 kWh.

What is 3,412 BTU in kilowatt-hours?

3,412 BTU is 0.999958 kWh (about 1 kWh).

How do I convert kilowatt-hours back to BTU?

Multiply by 3412.141633, or press the ⇄ swap button above. For example, 0.999958 kWh × 3412.141633 = 3,412 BTU.

What is the difference between BTU and BTU/h?

BTU is an amount of energy, while BTU per hour is power (energy per hour). Air conditioners are sold by BTU/h, even though the label often just says 'BTU'. 12,000 BTU/h equals one ton of refrigeration (3.517 kW).

Is a kWh the same as a kW?

No. kW is power (how fast energy is used) and kWh is energy (power × time). A 2 kW heater running for 3 hours uses 6 kWh.
