Factor1 t/hr = 277777.8 mg/s

Converter

t/hr

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

Result
277778mg/s

Rendered to 6 significant figures.

Formula

Formula
mg/s = t/hr × 277777.8

Multiply any value in metric tonnes per hour by 277777.8 to obtain the value in milligrams per second.

Worked example

Convert 1 t/hr to mg/s.

  1. 01Start with 1 t/hr.
  2. 02Multiply by the conversion factor: 1 × 277777.8 = 277778 mg/s.
Result1 t/hr = 277778 mg/s

FAQ

What is the conversion factor from t/hr to mg/s?
1 t/hr equals 277777.8 mg/s. To convert, multiply the value in metric tonnes per hour by 277777.8.
How do I convert 1 t/hr to mg/s?
1 t/hr = 277778 mg/s. For any value, multiply by 277777.8.
How do I convert mg/s back to t/hr?
Divide by the same factor — or equivalently, multiply by 3.6e-6. So 1 mg/s = 3.6e-6 t/hr.
When would I need to convert metric tonne per hour to milligram per second?
Mass flow conversions between t/hr and mg/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).
