Converter

kW

Accepts numbers or expressions, e.g. 150 + 14.7

Result
947.817BTU/s

Rendered to 6 significant figures.

Formula

Formula
BTU/s = kW × 0.9478171

Multiply any value in kilowatts by 0.9478171 to obtain the value in British thermal units per second.

Worked example

Convert 1000 kW to BTU/s.

  1. 01Start with 1000 kW.
  2. 02Multiply by the conversion factor: 1000 × 0.9478171 = 947.817 BTU/s.
Result1000 kW = 947.817 BTU/s

FAQ

What is the conversion factor from kW to BTU/s?
1 kW equals 0.9478171 BTU/s. To convert, multiply the value in kilowatts by 0.9478171.
How do I convert 1 kW to BTU/s?
1 kW = 0.947817 BTU/s. For any value, multiply by 0.9478171.
How do I convert BTU/s back to kW?
Divide by the same factor — or equivalently, multiply by 1.055056. So 1 BTU/s = 1.05506 kW.
When would I need to convert kilowatt to British thermal unit per second?
Power conversions are common when comparing motor ratings (often kW or hp), thermal duty (BTU/hr or kW), and utility consumption in mixed-unit projects.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
