Mass Flow Rate
mg/hrtog/hr
Convert milligrams per hour (mg/hr) to grams per hour (g/hr).
Factor1 mg/hr = 0.001 g/hr
Converter
mg/hr
Accepts numbers or expressions, e.g. 150 + 14.7
Result

Rendered to 6 significant figures.
Formula
Formula
g/hr = mg/hr × 0.001
Multiply any value in milligrams per hour by 0.001 to obtain the value in grams per hour.
Worked example
Convert 1000 mg/hr to g/hr.
- 01Start with 1000 mg/hr.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 g/hr.
Result1000 mg/hr = 1 g/hr

FAQ
What is the conversion factor from mg/hr to g/hr?
1 mg/hr equals 0.001 g/hr. To convert, multiply the value in milligrams per hour by 0.001.
How do I convert 1 mg/hr to g/hr?
1 mg/hr = 0.001 g/hr. For any value, multiply by 0.001.
How do I convert g/hr back to mg/hr?
Divide by the same factor — or equivalently, multiply by 1000. So 1 g/hr = 1000 mg/hr.
When would I need to convert milligram per hour to gram per hour?
Mass flow conversions between mg/hr and g/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).
