Metre Cube per Hour to CFM: A Comprehensive Guide for Professionals

Converting cubic meters per hour (m³/hr) to cubic feet per minute (CFM) is crucial in various industries, including ventilation, air conditioning, and process engineering. This guide provides a comprehensive understanding of the conversion process and its practical applications.

Measurement Equivalence and Conversion Formula

1 cubic meter per hour (m³/hr) is equivalent to 35.3 cubic feet per minute (CFM). The conversion formula is:

CFM = m³/hr × 35.314

For example, to convert 100 m³/hr to CFM:

CFM = 100 m³/hr × 35.314 ≈ 3,531 CFM
