### 5/5 — Righteous

*2024-05-25*

Didn’t think it’d be hard to find a fraction to mm converter app esp since more & more amz products shamelessly list their specs in metric units forcing you to ‘do the math’.  Many calcs simply miss the mark, most of which don’t convert fractions but if they do , either they don’t convert to metric or: convert in only one direction, typically require too many convoluted steps in getting from a to b , crowded & cluttered with other ‘stuff’, or so dumbed down and/or backfilled with romper room theme colors it’s insulting and nauseating at the same time. This app managed to nail it. It is intuitive, direct, no frills,  and to the point, getting your answer immediately without distraction. Yes it’d be nice if it offered a toggle for inch/feet/yards and mm/cm/m but Ill take it.  It gets you there and does the math effortlessly
