[FREE] Math Capacity Units Converter Extension 🧪

Hi everyone,

Today I am presenting you my brand new extension: Capacity Units! :test_tube: :test_tube: :test_tube:

1. Introduction

This extension helps you convert 2 different types of capacity units to each other: milliliters (mL) and liters (L).

Currently this is easy, no documentation is needed.

Next version: add cubic centimeters / decimeters / meters

great to see, that you are learning to create extensions...it is a nice start...
however the goal in creating extensions should be to provide solutions, which are not possible using existing blocks...

you might understand, that we do not really need another extension, which is able to divide or multiply by 1000 or similar...
