Gas Flow Unit Conversion Calculator: Cubic Meters per Hour (m³/h) to Standard Cubic Feet per Minute (SCFM)

Equipment sizing, system calibration, data reporting, and compliance depend on unit conversion between metric and imperial gas flow standards in globally networked industrial processes ranging from oil & gas to pharmaceutical and environmental control. One such important conversion frequently used by process designers and instrumentation experts is from Cubic Meters per Hour (m³/h) to Standard Cubic Feet per Minute (SCFM).

This conversion calculator article provides the definition, conversion formula, example calculations, and a user-friendly calculator to help engineers seamlessly convert metric flow values to their imperial counterparts.

m³/h to SCFM Gas Flow Conversion Calculator

The converter below allows you quickly convert Standard Cubic Feet per Minute (SCFM) from Cubic Meters per Hour (m³/h). This calculator helps real-time gas flow unit conversions for field engineers, design teams, and automation experts.

Conversion Formula:

Flow in SCFM = Flow in m³/h × 0.588578

Simply enter the m³/h value; the outcome will show in SCFM.

Definition: Cubic Meters per Hour (m³/h)

A metric tool measuring the volumetric flow rate of a gas or liquid is Cubic Meters per Hour (m³/h). Regions and businesses running under the International System of Units (SI) widely use this unit. Unless otherwise stated, it usually assumes normal ambient temperature and standard atmospheric pressure in gas flow applications.

Key Applications of m³/h:

• Measurement of process gas in chemical and refinery facilities
• Air supply control in ventilation and HVAC systems
• Flow recording in distributed control systems and SCADA
• Tracking of utility use in enterprises and facilities
• Equipment specification in worldwide supply designs

Definition: Standard Cubic Feet per Minute (SCFM)

Standard Cubic Feet per Minute (SCFM) is the volume of gas usually air or natural gas moved every minute at “standard conditions” (14.696 psi and 60°F or 101.325 kPa and 15.56°C). Commonly used in North America and by legacy equipment makers, it is an imperial unit.

Key Applications of SCFM:

• Sizing and specification of compressors
• Furnaces and kilns’ gas delivery systems
• Pneumatic systems’ flow control
• Legacy reporting and instrument calibration
• Sizing gas meters, orifice plates, and control valves

Example Calculation

If your gas system reports a flow rate of 100 m³/h, convert it to SCFM as:

SCFM = 100 × 0.588578 = 58.8578 SCFM

So, 100 m³/h = approximately 58.86 SCFM.

Uses of m³/h to SCFM Conversion

• Connecting current SI-based flow meters to legacy SCFM-based equipment
• Transforming flow data for documentation of multinational projects
• Maintaining consistency between imperial-based controllers and PLC/DCS flow records
• Helping suppliers choose pneumatic equipment and compressors.
• Examining energy statistics or gas use figures for regulatory filings.

Who Should Use This Conversion?

• Instrumentation engineers operating on mixed-unit systems
• Mechanical designers setting up compressed air systems or HVAC
• Project engineers globalizing gas flow documentation standardization
• Teams commissioning matching SCFM-based equipment specifications with field data
• Officers in compliance checking emissions or consumption reports across criteria
