Formula
g/s = lb/hr × 0.1259979
Multiply any value in pounds per hour by 0.1259979 to obtain the value in grams per second.
Worked example
Convert 100 lb/hr to g/s.
- 01Start with 100 lb/hr.
- 02Multiply by the conversion factor: 100 × 0.1259979 = 12.5998 g/s.
Result100 lb/hr = 12.5998 g/s

FAQ
What is the conversion factor from lb/hr to g/s?
1 lb/hr equals 0.1259979 g/s. To convert, multiply the value in pounds per hour by 0.1259979.
How do I convert 1 lb/hr to g/s?
1 lb/hr = 0.125998 g/s. For any value, multiply by 0.1259979.
How do I convert g/s back to lb/hr?
Divide by the same factor — or equivalently, multiply by 7.936641. So 1 g/s = 7.93664 lb/hr.
When would I need to convert pound per hour to gram per second?
Mass flow conversions between lb/hr and g/s 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).
