How to Convert Pound/hour square foot to Gram/second/square meter

Converting Pound/hour square foot (lb/(h·ft²)) to Gram/second/square meter (g/(s·m²)) is a core calculation in Mass Flux Density, which measures the mass flow rate of a substance moving across a unit surface area per unit 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 square foot equals 1.35623 Gram/second/square meter, while 1 g/(s·m²) equals 0.737338 lb/(h·ft²).

Direct Factor1 lb/(h·ft²) = 1.35623 g/(s·m²)

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 square meter (kg/(s·m²))) 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·ft²) = 0.00135623 kilogram per second square meter (kg/(s·m²))

2. Target SI Bridge (k_target):1 g/(s·m²) = 0.001 kilogram per second square meter (kg/(s·m²))

Step-by-step substitution for Pound/hour square foot → Gram/second/square meter:V(g/(s·m²)) = V(lb/(h·ft²)) × ( 0.00135623 / 0.001 ) = V(lb/(h·ft²)) × 1.35623
