📏 LEGO Unit Converter

Type a length in any field and every other unit follows — studs, plates, bricks, minifigs, track links, metric and imperial. Set a scale and the right-hand column shows what that size becomes in a model. Credits: rebuilt from the converter Sariel published at studs.sariel.pl.

Everything is worked out on this device. Nothing is sent anywhere and nothing is stored.
