Factor1 mg/hr = 2.4e-5 kg/day

Converter

mg/hr

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

Result
2.4kg/day

Rendered to 6 significant figures.

Formula

Formula
kg/day = mg/hr × 2.4e-5

Multiply any value in milligrams per hour by 2.4e-5 to obtain the value in kilograms per day.

Worked example

Convert 100000 mg/hr to kg/day.

  1. 01Start with 100000 mg/hr.
  2. 02Multiply by the conversion factor: 100000 × 2.4e-5 = 2.4 kg/day.
Result100000 mg/hr = 2.4 kg/day

FAQ

What is the conversion factor from mg/hr to kg/day?
1 mg/hr equals 2.4e-5 kg/day. To convert, multiply the value in milligrams per hour by 2.4e-5.
How do I convert 1 mg/hr to kg/day?
1 mg/hr = 2.4e-5 kg/day. For any value, multiply by 2.4e-5.
How do I convert kg/day back to mg/hr?
Divide by the same factor — or equivalently, multiply by 41666.67. So 1 kg/day = 41666.7 mg/hr.
When would I need to convert milligram per hour to kilogram per day?
Mass flow conversions between mg/hr and kg/day 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).
