CFM to L/s Converter

About This Tool

This conversion tool provides fast, precise translation of air flow from cubic feet per minute (CFM) to liters per second (L/s). It targets HVAC engineers, facility managers, researchers, and technicians who size ducts, compare equipment, or verify published specifications. By delivering a single, deterministic result from a numeric CFM input, it supports quick feasibility checks and design decisions without requiring manual calculations.
The calculation uses the standard conversion constant: 1 CFM = 0.47194745 L/s. Conceptually, the tool multiplies the input CFM value by this factor to produce L/s. It accepts decimal inputs and returns a numeric output in L/s with user-controlled precision, enabling alignment with project tolerances and reporting formats. There is no density or temperature correction; the result reflects idealized flow under standard conditions.
Who benefits include HVAC designers, building engineers, lab operators, and energy consultants who need reliable unit conversion to support duct sizing, ventilation rates, and performance testing. The tool differentiates itself with real-time results from a minimal input footprint, clear numeric outputs, and a straightforward single-value workflow suitable for quick checks in both imperial and metric contexts.
Core capabilities include a real-time, single-field conversion, validation of non-negative inputs, and precise formatting. Optional features in broader toolkits may include reverse conversions, batch processing, or exports; however, this tool focuses on one-way CFM to L/s, with exact constants and straightforward interpretation suitable for integration into larger calculation pipelines.
