BTU to kWh Calculator

Convert BTU to kWh (or reverse kWh to BTU) instantly—bidirectional energy conversion for heat quantity vs electricity use. This is not BTU/h power.

Calculator

Quick: BTU → kWh. Advanced: reverse to kWh → BTU.

Conversion direction

Energy (BTU) Example: 1000 BTU of heat energy (not BTU/h). Use IT factor ÷ 3412.141633 for kWh.

About this calculator

This BTU to kWh calculator is an energy converter (BTU ↔ kWh). It is not a power converter—for BTU/h ↔ W/kW use the Watts to BTU calculator. Browse the power calculator hub.

Calculation Results

≈ 0.293 kWh

1000 BTU → 0.293 kWh (energy)

Formula: kWh = BTU ÷ 3412.141633

BTU and kWh are energy quantities. Do not confuse with BTU/h (power). Estimates use the International Table (IT) factor; verify against project standards when required.

BTU to kWh formula

BTU → kWh: kWh = BTU ÷ 3412.141633

kWh → BTU: BTU = kWh × 3412.141633

BTU — British thermal unit (energy / heat quantity)
kWh — kilowatt-hour (electrical or thermal energy)
IT factor — 1 kWh = 3412.141633 BTU (International Table)

Example: 1000 ÷ 3412.141633 ≈ 0.293 kWh.

Frequently Asked Questions

How do I convert BTU to kWh?

Divide BTU by 3412.141633. Example: 1000 BTU ≈ 0.293 kWh. This converts heat energy, not BTU/h power.

How do I convert kWh to BTU?

Multiply kWh by 3412.141633. Example: 1 kWh ≈ 3412.14 BTU.

What is the difference between BTU and BTU/h?

BTU is energy (quantity of heat). BTU/h is power (rate). This page is energy only. For BTU/h ↔ W/kW use Watts to BTU.

What is 1000 BTU in kWh?

1000 ÷ 3412.141633 ≈ 0.293 kWh. Use the 1000 BTU preset above.

Is this the same as the Watts to BTU calculator?

No. Watts to BTU converts power (W/kW ↔ BTU/h). This page converts energy (BTU ↔ kWh). Do not mix BTU with BTU/h.
