Formula
Formula
g/s = st/hr × 251.9958
Multiply any value in short tons per hour by 251.9958 to obtain the value in grams per second.
Worked example
Convert 1 st/hr to g/s.
- 01Start with 1 st/hr.
- 02Multiply by the conversion factor: 1 × 251.9958 = 251.996 g/s.
Result1 st/hr = 251.996 g/s

FAQ
What is the conversion factor from st/hr to g/s?
1 st/hr equals 251.9958 g/s. To convert, multiply the value in short tons per hour by 251.9958.
How do I convert 1 st/hr to g/s?
1 st/hr = 251.996 g/s. For any value, multiply by 251.9958.
How do I convert g/s back to st/hr?
Divide by the same factor — or equivalently, multiply by 0.003968321. So 1 g/s = 0.00396832 st/hr.
When would I need to convert short ton per hour to gram per second?
Mass flow conversions between st/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).
