How to Convert Gram/second to Pound/hour

Converting Gram/second (g/s) to Pound/hour (lb/h) is a core calculation in Mass Flow Rate, which measures the mass of a substance moving through a cross-sectional area per unit of time. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Gram/second equals 7.936641 Pound/hour, while 1 lb/h equals 0.125998 g/s.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (kilogram per second (kg/s)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 g/s = 0.001 kilogram per second (kg/s)

2. Target SI Bridge (k_target):1 lb/h = 0.000125998 kilogram per second (kg/s)

Step-by-step substitution for Gram/second → Pound/hour:V(lb/h) = V(g/s) × ( 0.001 / 0.000125998 ) = V(g/s) × 7.936641

Mathematical FormulaValue in Pound/hour = Value in Gram/second × 7.93664144Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Gram/second (g/s) to Pound/hour (lb/h): multiply 120 by 7.936641 to get 952.396973 lb/h. At an industrial engineering scale, 5000 g/s converts to 39683.2072 lb/h.

Inverse check: 1 lb/h = 0.125998 g/s.
