How many CFM is 1 liter per minute?

1 liter per minute equals approximately 0.0353147 cubic feet per minute (CFM). For quick mental math, multiply L/min by roughly 0.0353 to get CFM.

How do I convert L/min to CFM manually?

Multiply the L/min value by 0.0353146667. For example, 100 L/min × 0.0353146667 = 3.5315 CFM. The factor comes from 1 cubic foot = 28.316846592 liters.

What is the difference between L/min and CFM?

L/min (liters per minute) is a metric volumetric flow rate unit common in science and engineering outside North America. CFM (cubic feet per minute) is used in the United States for HVAC, ventilation, and air equipment specifications.

What CFM is needed to ventilate a room?

A general rule is 1 CFM per square foot of floor space for standard rooms. Kitchens and bathrooms typically require 50–100 CFM of spot ventilation. A 100 m² home ventilated at 0.35 air changes/hour needs roughly 100–120 CFM depending on ceiling height.

Why do air compressors use CFM instead of L/min?

CFM is the traditional US industry standard for pneumatic tools and compressors. Most American tool manufacturers rate air consumption in CFM, so contractors and technicians in the US use CFM to match tools to compressor capacity without extra conversion.
