Laser speed & settings converter

Convert a speed between millimeters or inches, per second or per minute. The calculation preserves the speed. It does not establish the power, passes or other conditions for a different laser. Keep the machine and source context with any setting you use.

Convert a speed

The starting value demonstrates arithmetic only. It is not a suggested laser setting.

10 mm/s

600 mm/min = 10 mm/s. The result is rounded for display.

What the calculation does

One minute contains 60 seconds. To convert mm/min to mm/s, divide by 60. To convert inches to millimeters, multiply by 25.4: NIST defines one inch as exactly 25.4 mm. The starting example, 600 mm/min, equals 10 mm/s.

LightBurn's speed documentation tells users to match distance and time units or convert them. It also explains why the machine may not reach the entered speed.

Save the context with the number

Use the LightBurn library guide to organize presets. Read how CutChart records a source and the available tools before treating a calculation as a documented recipe.

Moving settings between machines

A unit conversion does not create a target-machine setting. The target needs its own documented observation for the same material, operation and thickness.

Look up a documented target setting

The target must have its own complete observation for the same material, operation and thickness.

No complete settings are available for this lookup yet.

Manufacturer-published reference rows are on the diode and CO2 settings pages. Each row belongs to the machine that published it and is not moved to another machine, so this lookup stays empty until a complete documented observation exists for both machines.

Common questions

Does a unit conversion change the power percentage?

No. This tool changes only the speed unit. Power percentage, passes, focus and other settings are outside the calculation.

Can I use the result on a different laser?

The result describes the same speed in another unit. It does not establish suitable settings for another machine, material or operation.

NIST states the exact inch-to-millimeter relationship. This factor converts length units; it does not describe laser performance.

Always pay attention to units of distance and time when entering Speed settings
The speed section calls for matching units or converting them before entering a recommendation.
