How to Convert Pound/hour to Ton (metric)/second

Converting Pound/hour (lb/h) to Ton (metric)/second (t/s) 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 1.259979 × 10⁻⁷ Ton (metric)/second, while 1 t/s equals 7936641.44 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 t/s = 1000 kilogram per second (kg/s)

Step-by-step substitution for Pound/hour → Ton (metric)/second:V(t/s) = V(lb/h) × ( 0.000125998 / 1000 ) = V(lb/h) × 1.259979 × 10⁻⁷

Mathematical FormulaValue in Ton (metric)/second = Value in Pound/hour × 1.25997881 × 10⁻⁷Direct computational formula applied for standard conversion.

Worked Example

Converting 250 lb/h yields an exact output of 3.149947 × 10⁻⁵ t/s in Ton (metric)/second. Under higher industrial throughput, 5000 lb/h translates to 0.000629989 t/s.

Inverse check: 1 t/s = 7936641.44 lb/h.
