How to Convert Pound/hour to Kilogram/minute

Converting Pound/hour (lb/h) to Kilogram/minute (kg/min) 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 Pound/hour equals 0.00755987 Kilogram/minute, while 1 kg/min equals 132.277357 lb/h.

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 lb/h = 0.000125998 kilogram per second (kg/s)

2. Target SI Bridge (k_target):1 kg/min = 0.0166667 kilogram per second (kg/s)

Step-by-step substitution for Pound/hour → Kilogram/minute:V(kg/min) = V(lb/h) × ( 0.000125998 / 0.0166667 ) = V(lb/h) × 0.00755987

Mathematical FormulaValue in Kilogram/minute = Value in Pound/hour × 0.0075598728Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 12 Pound/hour (lb/h) produces 0.0907185 Kilogram/minute (kg/min). In heavy-duty utility and industrial workloads, 240 lb/h equals 1.814369 kg/min.

Inverse check: 1 kg/min = 132.277357 lb/h.
