FAQ

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