Pound per second quick reference
| Pound per second | Kilogram per second | Kilogram per hour | Pound per hour |
|---|---|---|---|
| 1 lb/s | = 0.45359237 kg/s | = 1632.932532 kg/h | = 3600 lb/h |
| 10 lb/s | = 4.5359237 kg/s | = 16329.32532 kg/h | = 36000 lb/h |
| 100 lb/s | = 45.359237 kg/s | = 163293.2532 kg/h | = 360000 lb/h |
| 1000 lb/s | = 453.59237 kg/s | = 1632932.532 kg/h | = 3600000 lb/h |
