FAQ
What is the conversion factor from kg/day to lb/day?
1 kg/day equals 2.204623 lb/day. To convert, multiply the value in kilograms per day by 2.204623.
How do I convert 1 kg/day to lb/day?
1 kg/day = 2.20462 lb/day. For any value, multiply by 2.204623.
How do I convert lb/day back to kg/day?
Divide by the same factor — or equivalently, multiply by 0.4535924. So 1 lb/day = 0.453592 kg/day.
When would I need to convert kilogram per day to pound per day?
Mass flow conversions between kg/day and lb/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).
