Kilogram per second quick reference
| Kilogram per second | Tonne per hour | Pound per second | Kilogram per hour |
|---|---|---|---|
| 1 kg/s | = 3.6 t/h | ≈ 2.204622622 lb/s | = 3600 kg/h |
| 10 kg/s | = 36 t/h | ≈ 22.04622622 lb/s | = 36000 kg/h |
| 100 kg/s | = 360 t/h | ≈ 220.4622622 lb/s | = 360000 kg/h |
| 1000 kg/s | = 3600 t/h | ≈ 2204.622622 lb/s | = 3600000 kg/h |
