How to convert kilograms per square meter hour to pounds per square foot second
Mass flux combines mass flow and area. Keep the area normal to the flow and use the same signed-direction convention when comparing data.
Use x for the value in kg/(m²·h), b for the intermediate value in kg/(m²·s), and y for the result in lb/(ft²·s).
lb/(ft²·s) = kg/(m²·h) × 0.0002777777777777778 ÷ 4.88242763638305
Worked examples
10 kg/(m²·h) ≈ 0.000568933732285 lb/(ft²·s)
Step 1: (10 × 0.000277777777778) ≈ 0.00277777777778 kg/(m²·s).
Step 2: 0.00277777777778 ÷ 4.88242763638 ≈ 0.000568933732285 lb/(ft²·s).20 kg/(m²·h) ≈ 0.00113786746457 lb/(ft²·s)
Step 1: (20 × 0.000277777777778) ≈ 0.00555555555556 kg/(m²·s).
Step 2: 0.00555555555556 ÷ 4.88242763638 ≈ 0.00113786746457 lb/(ft²·s).
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kilograms per square meter hour
Kilograms per square meter hour (kg/(m²·h)) measures mass flux density under the conventions above. The base value in kg/(m²·s) is (x × 0.000277777777778), where x is the numerical value in kg/(m²·h). Factors shown here are rounded for display; calculations use the stored factor.
About Pounds per square foot second
Pounds per square foot second (lb/(ft²·s)) measures mass flux density under the conventions above. The base value in kg/(m²·s) is (x × 4.88242763638), where x is the numerical value in lb/(ft²·s). Factors shown here are rounded for display; calculations use the stored factor.
