Formula

Formula
J/s = kgf·m/s × 9.80665

Multiply any value in kilograms-force metre per second by 9.80665 to obtain the value in joules per second.

Worked example

Convert 10 kgf·m/s to J/s.

  1. 01Start with 10 kgf·m/s.
  2. 02Multiply by the conversion factor: 10 × 9.80665 = 98.0665 J/s.
Result10 kgf·m/s = 98.0665 J/s

FAQ

What is the conversion factor from kgf·m/s to J/s?
1 kgf·m/s equals 9.80665 J/s. To convert, multiply the value in kilograms-force metre per second by 9.80665.
How do I convert 1 kgf·m/s to J/s?
1 kgf·m/s = 9.80665 J/s. For any value, multiply by 9.80665.
How do I convert J/s back to kgf·m/s?
Divide by the same factor — or equivalently, multiply by 0.1019716. So 1 J/s = 0.101972 kgf·m/s.
When would I need to convert kilogram-force metre per second to joule 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).
