Pounds per hour to Kilograms per hour
1 pound per hour = 0.45359 kilograms per hour · 1 kg/h = 2.2046 lb/h
1 pound per hour = 0.45359 kilograms per hour
How it’s calculated
kg/h = lb/h × 0.45359237
- Multiply the value in pounds per hour by 0.45359237.
- To go back, divide by 0.45359237 (or multiply by 2.204622622).
- 1 lb/h = 0.45359237 kg/h · 1 kg/h = 2.204622622 lb/h
