How to convert pounds per hour to kilograms per hour
A mass flow rate cannot become a volumetric flow rate without fluid density. This conversion preserves mass per time and does not assume water or any other substance.
Use x for the value in lb/h, b for the intermediate value in kg/s, and y for the result in kg/h.
kg/h = lb/h × 0.00012599788055555556 ÷ 0.0002777777777777778
Worked examples
10 lb/h ≈ 4.5359237 kg/h
Step 1: (10 × 0.000125997880556) ≈ 0.00125997880556 kg/s.
Step 2: 0.00125997880556 ÷ 0.000277777777778 ≈ 4.5359237 kg/h.20 lb/h ≈ 9.0718474 kg/h
Step 1: (20 × 0.000125997880556) ≈ 0.00251995761111 kg/s.
Step 2: 0.00251995761111 ÷ 0.000277777777778 ≈ 9.0718474 kg/h.
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 Pounds per hour
Pounds per hour (lb/h) measures flow mass under the conventions above. The base value in kg/s is (x × 0.000125997880556), where x is the numerical value in lb/h. Factors shown here are rounded for display; calculations use the stored factor.
About Kilograms per hour
Kilograms per hour (kg/h) measures flow mass under the conventions above. The base value in kg/s is (x × 0.000277777777778), where x is the numerical value in kg/h. Factors shown here are rounded for display; calculations use the stored factor.
