Mass Flow Rate Converter — kg/s, kg/h & lb/h

Convert between kilograms per second, kilograms per hour, tonnes per hour, and pounds per hour.

—
How this conversion works. Every rate is converted through kg/s (SI); time factors are exact fractions and the pound uses the exact NIST definition in NIST Special Publication 811.

Frequently asked questions

How do I convert kilogram per hour to pound per hour?

1 kilogram per hour = 2.20462 pound per hour. Choose "Kilogram per hour (kg/h)" as From and "Pound per hour (lb/h)" as To, type a value, and the result updates instantly.

How do I convert kg/h to lb/h?

Multiply by 2.20462: 100 kg/h = 220.46 lb/h. The factor is the exact pound definition, 1 lb = 0.45359237 kg.

How do I get mass flow from volumetric flow?

Multiply volumetric flow by density: ṁ = ρ × Q. Water at 10 L/min is about 10 kg/min; air at the same flow is roughly 800× less mass.

Is my data sent to a server?

No. Conversions run entirely in your browser using fixed factors — nothing is uploaded or logged.
