How to convert kilograms per hour to kilograms per second
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 kg/h, b for the intermediate value in kg/s, and y for the result in kg/s.
kg/s = kg/h × 0.0002777777777777778
Worked examples
10 kg/h ≈ 0.00277777777778 kg/s
Step 1: (10 × 0.000277777777778) ≈ 0.00277777777778 kg/s.
Step 2: 0.00277777777778 ÷ 1 ≈ 0.00277777777778 kg/s.20 kg/h ≈ 0.00555555555556 kg/s
Step 1: (20 × 0.000277777777778) ≈ 0.00555555555556 kg/s.
Step 2: 0.00555555555556 ÷ 1 ≈ 0.00555555555556 kg/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 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.
About Kilograms per second
Kilograms per second (kg/s) measures flow mass under the conventions above. The base value in kg/s is (x × 1), where x is the numerical value in kg/s. Factors shown here are rounded for display; calculations use the stored factor.
