How to Convert Square meter/hour to Square foot/second

Converting Square meter/hour (m²/h) to Square foot/second (ft²/s) is a core calculation in Kinematic Viscosity, which measures a fluid's resistive flow under the influence of gravity (dynamic viscosity divided by density). 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 Square meter/hour equals 0.00298998 Square foot/second, while 1 ft²/s equals 334.450957 m²/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 (square meter per second (m²/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 m²/h = 0.000277778 square meter per second (m²/s)

2. Target SI Bridge (k_target):1 ft²/s = 0.092903 square meter per second (m²/s)

Step-by-step substitution for Square meter/hour → Square foot/second:V(ft²/s) = V(m²/h) × ( 0.000277778 / 0.092903 ) = V(m²/h) × 0.00298998

Mathematical FormulaValue in Square foot/second = Value in Square meter/hour × 0.002989975Direct computational formula applied for standard conversion.

Worked Example

To convert 12 Square meter/hour (m²/h) to Square foot/second (ft²/s): multiply 12 by 0.00298998 to get 0.0358797 ft²/s. At an industrial engineering scale, 1000 m²/h converts to 2.989975 ft²/s.

Inverse check: 1 ft²/s = 334.450957 m²/h.
