BTU/h to kW formula
The calculator converts the input to the category's reference unit, then divides by the target unit's factor.
Result = input × source factor ÷ target factor
1 × (0.293071070172 ÷ 1,000) ≈ 0.000293071
Worked example: 1 British thermal units per hour ≈ 0.000293071 Kilowatts
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.

Frequently asked questions
how many kW is 1 BTU/h?
1 British thermal units per hour ≈ 0.000293071 Kilowatts. Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
how to convert BTU/h to kW?
The calculator converts the input to the category's reference unit, then divides by the target unit's factor. 1 × 0.000293071070172 ≈ 0.000293071 Kilowatts. Use the source and target factors shown in the formula. The worked example uses the value on this page, and the table provides other common values.
Why do horsepower results differ?
Mechanical horsepower, metric horsepower, electrical horsepower and boiler horsepower use different definitions. Select the definition matching your source document.
Why is the displayed result rounded?
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
What input range can I use?
This calculator accepts non-negative values up to 1 trillion, with up to 8 decimal places. It does not calculate signed vectors or calendar date intervals.
Why is a unit unavailable?
A conversion is unavailable when a verified unit definition or a current exchange-rate value has not been configured. The tool does not invent a coefficient.
