How to convert cubic meters per hour to cubic meters per second
Gas volumes must refer to the same temperature and pressure. Standard and actual cubic flow rates cannot be equated without state information; US gallons here are liquid gallons.
Use x for the value in m³/h, b for the intermediate value in m³/s, and y for the result in m³/s.
m³/s = m³/h × 0.0002777777777777778
Worked examples
10 m³/h ≈ 0.00277777777778 m³/s
Step 1: (10 × 0.000277777777778) ≈ 0.00277777777778 m³/s.
Step 2: 0.00277777777778 ÷ 1 ≈ 0.00277777777778 m³/s.20 m³/h ≈ 0.00555555555556 m³/s
Step 1: (20 × 0.000277777777778) ≈ 0.00555555555556 m³/s.
Step 2: 0.00555555555556 ÷ 1 ≈ 0.00555555555556 m³/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 Cubic meters per hour
Cubic meters per hour (m³/h) measures flow under the conventions above. The base value in m³/s is (x × 0.000277777777778), where x is the numerical value in m³/h. Factors shown here are rounded for display; calculations use the stored factor.
About Cubic meters per second
Cubic meters per second (m³/s) measures flow under the conventions above. The base value in m³/s is (x × 1), where x is the numerical value in m³/s. Factors shown here are rounded for display; calculations use the stored factor.
