How to Convert Pound per Second to Gram per Second
- 1 lb/s = 453.59237 g/s
- 1 g/s = 0.002204622622 lb/s
- Example: convert 15 lb/s to g/s: 15 lb/s = 15 × 453.59237 g/s = 6803.88555 g/s
Formula
g/s = lb/s × 453.59237
Derivation from SI units:
- 1 lb/s = 0.45359237 kg/s.
- 1 g/s = 10⁻³ kg/s.
- 1 lb/s = 0.45359237 kg/s ÷ 0.001 kg/s per g/s = 453.59237 g/s
Both units are defined exactly, so the factor is exact. Pound per Second definition: pound per second; Gram per Second definition: gram per second.
Worked examples
- A reading of 10 lb/s converts to 4535.9237 g/s.
10 lb/s × 453.59237 = 4535.9237 g/s - A value of 200 lb/s is 90718.474 g/s.
200 lb/s × 453.59237 = 90718.474 g/s
