1. What is CFM to M3/H Conversion?

The CFM (cubic feet per minute) to M3/H (cubic meters per hour) conversion is used to convert airflow or volumetric flow rates between imperial and metric units. This is commonly needed in HVAC, ventilation, and industrial applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( CFM \) — Cubic feet per minute (imperial unit)
• \( M3H \) — Cubic meters per hour (metric unit)
• \( 1.699 \) — Conversion factor (exact value is 1.6990108)

Explanation: The conversion accounts for both the volume difference (1 cubic foot = 0.0283168 cubic meters) and the time difference (1 hour = 60 minutes).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential when working with international equipment specifications, comparing system performance, or complying with different regional standards.

4. Using the Calculator

Tips: Simply enter the CFM value and the calculator will automatically compute the equivalent M3/H. The input must be a positive number.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 1.699?
A: It combines the cubic feet to cubic meters conversion (1 ft³ = 0.0283168 m³) and minutes to hours conversion (60 minutes/hour).

Q2: How accurate is this conversion?
A: The conversion factor 1.699 is precise to four decimal places (1.6990108). For most practical applications, 1.699 provides sufficient accuracy.

Q3: When would I need this conversion?
A: When working with international equipment specifications, comparing ventilation systems, or converting between imperial and metric unit systems.

Q4: Can I convert M3/H back to CFM?
A: Yes, divide M3/H by 1.699 to get CFM (or multiply by 0.58858).

Q5: Are there other related conversions?
A: Yes, similar conversions exist for L/s (liters per second) and other flow rate units used in different industries.
