How to Convert Pound/hour to Pound/minute

Converting Pound/hour (lb/h) to Pound/minute (lb/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 0.0166667 Pound/minute, while 1 lb/min equals 60 lb/h.

Direct Factor1 lb/h = 0.0166667 lb/min

Inverse Ratio1 lb/min = 60 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 lb/min = 0.00755987 kilogram per second (kg/s)

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

Mathematical FormulaValue in Pound/minute = Value in Pound/hour × 0.016666667Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Pound/hour (lb/h) to Pound/minute (lb/min): multiply 120 by 0.0166667 to get 2 lb/min. At an industrial engineering scale, 240 lb/h converts to 4 lb/min.

Inverse check: 1 lb/min = 60 lb/h.
