Rendered to 6 significant figures.

Formula

Formula
kg/day = mg/s × 0.0864

Multiply any value in milligrams per second by 0.0864 to obtain the value in kilograms per day.

Worked example

Convert 100 mg/s to kg/day.

  1. 01Start with 100 mg/s.
  2. 02Multiply by the conversion factor: 100 × 0.0864 = 8.64 kg/day.
Result100 mg/s = 8.64 kg/day

FAQ

What is the conversion factor from mg/s to kg/day?
1 mg/s equals 0.0864 kg/day. To convert, multiply the value in milligrams per second by 0.0864.
How do I convert 1 mg/s to kg/day?
1 mg/s = 0.0864 kg/day. For any value, multiply by 0.0864.
How do I convert kg/day back to mg/s?
Divide by the same factor — or equivalently, multiply by 11.57407. So 1 kg/day = 11.5741 mg/s.
When would I need to convert milligram per second to kilogram per day?
Mass flow conversions between mg/s 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).
