g/hrtog/s
Convert grams per hour (g/hr) to grams per second (g/s).
Factor1 g/hr = 0.0002777778 g/s
Converter
g/hr
Accepts numbers or expressions, e.g. 150 + 14.7
Result
g/s
Rendered to 6 significant figures.
Formula
Formula
g/s = g/hr × 0.0002777778
Multiply any value in grams per hour by 0.0002777778 to obtain the value in grams per second.
Worked example
Convert 3600 g/hr to g/s.
- 01Start with 3600 g/hr.
- 02Multiply by the conversion factor: 3600 × 0.0002777778 = 1 g/s.
Result3600 g/hr = 1 g/s

FAQ
What is the conversion factor from g/hr to g/s?
1 g/hr equals 0.0002777778 g/s. To convert, multiply the value in grams per hour by 0.0002777778.
How do I convert 1 g/hr to g/s?
1 g/hr = 0.000277778 g/s. For any value, multiply by 0.0002777778.
How do I convert g/s back to g/hr?
Divide by the same factor — or equivalently, multiply by 3600. So 1 g/s = 3600 g/hr.
When would I need to convert gram per hour to gram per second?
Mass flow conversions between g/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).
