Calculator
Flow Converter
Convert flow between L/min, L/s, m3/h, mL/min, and US gpm.
Calculator Inputs
Flow value must be a valid number.
Legend
Flow conversion legend
Each flow value is converted through liters per minute as the base unit.
Input meaning
- L/min is common for oxygen therapy and medical gas outlets.
- m3/h is common in plant, compressor, and facility calculations.
- mL/min appears in small-flow lab and infusion contexts.
Result interpretation
- Converted volumetric flow does not correct for pressure, temperature, gas density, or standard conditions.
- Use calibrated flow analyzers for acceptance and PM.
Assumptions
- Volumetric units are treated as equivalent at the stated condition.
- No mass-flow or gas-law correction is applied.
Biomedical use
- Useful for oxygen planning, RO flow review, medical air/vacuum discussions, and service documentation.
How to identify the required values
Use these examples to choose values from gauges, labels, manuals, datasheets, or service reports.
| Field | Example value | Tip |
|---|---|---|
| Flow value | Oxygen flowmeter set to 10 L/min. | Use the displayed flow and confirm whether the device reports L/min, L/s, or m3/h. |
| From unit | m3/h from compressor datasheet. | Use the unit from the datasheet or flowmeter. |
| To unit | Convert m3/h to L/min for medical gas demand planning. | State converted units clearly in RFQs and service notes. |
Input Checklist
Confirm these values before relying on the output for procurement, PM, or service planning.

Safety And Engineering Notes
Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.
- Gas flow conversions assume equivalent volumetric flow units.
- Clinical flow settings should be verified on calibrated devices.
