Gram per Second (g/s)
Grams per second suit small flows: engine mass-air-flow sensors read in g/s (about 3 g/s per litre of engine at idle), as do laboratory feeds.
Symbol: g/s
Quantity: mass flow rate ṁ
SI relation: 1 g/s = 0.001 kg/s (exact)
Derivation: 1 g/s = 10⁻³ kg/s.
Exact: yes, by definition
Typical uses
- Automotive MAF sensors
- Laboratory and pilot-plant feeds
- Emission rates (g/s) in dispersion models
