How to Convert Metric ton/hour to Pound/second

Converting Metric ton/hour (t/h) to Pound/second (lb/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 Metric ton/hour equals 0.612395 Pound/second, while 1 lb/s equals 1.632933 t/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 t/h = 0.277778 kilogram per second (kg/s)

2. Target SI Bridge (k_target):1 lb/s = 0.453592 kilogram per second (kg/s)

Step-by-step substitution for Metric ton/hour → Pound/second:V(lb/s) = V(t/h) × ( 0.277778 / 0.453592 ) = V(t/h) × 0.612395

Mathematical FormulaValue in Pound/second = Value in Metric ton/hour × 0.61239517Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 75 t/h, applying the conversion factor yields exactly 45.929638 lb/s. At larger operational scale, 1000 Metric ton/hour corresponds to 612.395172 lb/s.

Inverse check: 1 lb/s = 1.632933 t/h.
