How to Convert Pound/second to Milligram/hour

Converting Pound/second (lb/s) to Milligram/hour (mg/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 Pound/second equals 1.632933 × 10⁹ Milligram/hour, while 1 mg/h equals 6.123952 × 10⁻¹⁰ lb/s.

Direct Factor1 lb/s = 1.632933 × 10⁹ mg/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/s = 0.453592 kilogram per second (kg/s)

2. Target SI Bridge (k_target):1 mg/h = 2.777778 × 10⁻¹⁰ kilogram per second (kg/s)

Step-by-step substitution for Pound/second → Milligram/hour:V(mg/h) = V(lb/s) × ( 0.453592 / 2.777778 × 10⁻¹⁰ ) = V(lb/s) × 1.632933 × 10⁹

Mathematical FormulaValue in Milligram/hour = Value in Pound/second × 1.63293253 × 10⁹Direct computational formula applied for standard conversion.

Worked Example

To convert 24 Pound/second (lb/s) to Milligram/hour (mg/h): multiply 24 by 1.632933 × 10⁹ to get 3.919038 × 10¹⁰ mg/h. At an industrial engineering scale, 100 lb/s converts to 1.632933 × 10¹¹ mg/h.

Inverse check: 1 mg/h = 6.123952 × 10⁻¹⁰ lb/s.
