Sm³/h to m³/h Converter
Sm³/h (Standard cubic meters per hour) and m³/h (actual cubic meters per hour) represent the same physical volume unit — one cubic meter per hour. The distinction is the reference...

Examples
1 sm3h
= 1 m³/h
1 Sm³/h = 1 m³/h (unit reference)
100 sm3h
= 100 m³/h
500 sm3h
= 500 m³/h
Quick Reference Table
| Sm³/h | m³/h |
|---|---|
| 1 | 1 |
| 10 | 10 |
| 50 | 50 |
| 100 | 100 |
| 500 | 500 |
| 1000 | 1000 |
Where is this used?
Use alongside temperature/pressure corrected converters for real gas flow calculations.
Frequently Asked Questions
Why is the conversion factor 1?
Both units measure cubic meters per hour. The conversion factor between the volumetric units themselves is 1. The difference is the reference temperature and pressure, which requires a separate gas law correction.
How do I correct for actual conditions?
Use the SCFM-to-ACFM or Nm³/h-to-m³/h converters that account for temperature and pressure. The gas law correction factor is (T_actual/T_std) × (P_std/P_actual).
What standard does Sm³ use?
Sm³ typically uses US Standard conditions: 60°F (15.6°C) and 14.696 psia. European Nm³ uses 0°C and 1.01325 bar. Always verify which standard is referenced in your documentation.
