Kilowatt-hours to BTU formula

BTU = kWh × 3412.141633

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

Example: 1 kWh × 3412.141633 = 3,412.14 BTU.

Reverse formula (BTU to kilowatt-hours): kWh = BTU ÷ 3412.141633. Example: 102,364 BTU ÷ 3412.141633 = 30 kWh.

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

About kilowatt-hours and BTU

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.

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.

Frequently asked questions

How many BTU in 1 kilowatt-hour?

One kilowatt-hour equals 3,412.14 BTU.

How do you convert kilowatt-hours to BTU?

Multiply the number of kilowatt-hours by 3412.141633. For example, 1 kWh × 3412.141633 = 3,412.14 BTU.

What is 30 kilowatt-hours in BTU?

30 kWh is 102,364 BTU (daily US home use (approx.)).

How much is 100 kilowatt-hours in BTU?

100 kilowatt-hours equals 341,214 BTU.

How do I convert BTU back to kilowatt-hours?

Divide by 3412.141633, or press the ⇄ swap button above. For example, 102,364 BTU ÷ 3412.141633 = 30 kWh.

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.
