Formula

Formula
kg/day = kg/s × 86400

Multiply any value in kilograms per second by 86400 to obtain the value in kilograms per day.

Worked example

Convert 1 kg/s to kg/day.

  1. 01Start with 1 kg/s.
  2. 02Multiply by the conversion factor: 1 × 86400 = 86400 kg/day.
Result1 kg/s = 86400 kg/day

FAQ

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