Formula

Formula
kg/s = kg/day × 1.157407e-5

Multiply any value in kilograms per day by 1.157407e-5 to obtain the value in kilograms per second.

Worked example

Convert 100000 kg/day to kg/s.

  1. 01Start with 100000 kg/day.
  2. 02Multiply by the conversion factor: 100000 × 1.157407e-5 = 1.15741 kg/s.
Result100000 kg/day = 1.15741 kg/s

FAQ

What is the conversion factor from kg/day to kg/s?
1 kg/day equals 1.157407e-5 kg/s. To convert, multiply the value in kilograms per day by 1.157407e-5.
How do I convert 1 kg/day to kg/s?
1 kg/day = 1.15741e-5 kg/s. For any value, multiply by 1.157407e-5.
How do I convert kg/s back to kg/day?
Divide by the same factor — or equivalently, multiply by 86400. So 1 kg/s = 86400 kg/day.
When would I need to convert kilogram per day to kilogram per second?
Mass flow conversions between kg/day and kg/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).
