Formula
Formula
kg/hr = kg/s × 3600
Multiply any value in kilograms per second by 3600 to obtain the value in kilograms per hour.
Worked example
Convert 1 kg/s to kg/hr.
- 01Start with 1 kg/s.
- 02Multiply by the conversion factor: 1 × 3600 = 3600 kg/hr.
Result1 kg/s = 3600 kg/hr

FAQ
What is the conversion factor from kg/s to kg/hr?
1 kg/s equals 3600 kg/hr. To convert, multiply the value in kilograms per second by 3600.
How do I convert 1 kg/s to kg/hr?
1 kg/s = 3600 kg/hr. For any value, multiply by 3600.
How do I convert kg/hr back to kg/s?
Divide by the same factor — or equivalently, multiply by 0.0002777778. So 1 kg/hr = 0.000277778 kg/s.
When would I need to convert kilogram per second to kilogram per hour?
Mass flow conversions between kg/s and kg/hr are common in material balances, process stream summaries, bulk solids handling, custody transfer, and equipment sizing where kg/hr, t/hr, lb/hr, and lb/s may all appear in different datasheets or vendor documents.
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).
