FAQ
What is the conversion factor from BTU/s to J/s?
1 BTU/s equals 1055.056 J/s. To convert, multiply the value in British thermal units per second by 1055.056.
How do I convert 1 BTU/s to J/s?
1 BTU/s = 1055.06 J/s. For any value, multiply by 1055.056.
How do I convert J/s back to BTU/s?
Divide by the same factor — or equivalently, multiply by 0.0009478171. So 1 J/s = 0.000947817 BTU/s.
When would I need to convert British thermal unit 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).
