Mass Flow Rate
g/stomg/hr
Convert grams per second (g/s) to milligrams per hour (mg/hr).
Factor1 g/s = 3600000 mg/hr
Converter
g/s
Accepts numbers or expressions, e.g. 150 + 14.7
Result
mg/hr
Rendered to 6 significant figures.
Formula
Formula
mg/hr = g/s × 3600000
Multiply any value in grams per second by 3600000 to obtain the value in milligrams per hour.
Worked example
Convert 1 g/s to mg/hr.
- 01Start with 1 g/s.
- 02Multiply by the conversion factor: 1 × 3600000 = 3.60000e+6 mg/hr.
Result1 g/s = 3.60000e+6 mg/hr

FAQ
What is the conversion factor from g/s to mg/hr?
1 g/s equals 3600000 mg/hr. To convert, multiply the value in grams per second by 3600000.
How do I convert 1 g/s to mg/hr?
1 g/s = 3.60000e+6 mg/hr. For any value, multiply by 3600000.
How do I convert mg/hr back to g/s?
Divide by the same factor — or equivalently, multiply by 2.777778e-7. So 1 mg/hr = 2.77778e-7 g/s.
When would I need to convert gram per second to milligram per hour?
Mass flow conversions between g/s and mg/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).
