mg/stomg/hr

Convert milligrams per second (mg/s) to milligrams per hour (mg/hr).

Factor1 mg/s = 3600 mg/hr

Converter

mg/s

Accepts numbers or expressions, e.g. 150 + 14.7

Result
3600mg/hr

Rendered to 6 significant figures.

Formula

Formula
mg/hr = mg/s × 3600

Multiply any value in milligrams per second by 3600 to obtain the value in milligrams per hour.

Worked example

Convert 1 mg/s to mg/hr.

  1. 01Start with 1 mg/s.
  2. 02Multiply by the conversion factor: 1 × 3600 = 3600 mg/hr.
Result1 mg/s = 3600 mg/hr

FAQ

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