Tool · one value, every unit
Compare a value in every unit
A single conversion tells you what a number becomes. This tells you where it sits: the same quantity written out in every unit the category has, ordered by size so the gaps between systems are visible rather than implied.
| Unit | Symbol | System | Value |

Reading the table
Every row is the value you typed, converted through the category's base unit in exact rational arithmetic and rounded once at the end. Rows that show a dash are units that cannot represent the value at all — a reciprocal unit such as litres per 100 km has no answer for zero, and says so rather than printing an infinity.
"Common units only" narrows it to the units that have their own conversion pages, which is usually what a reference table wants. The cheat sheets are the printable version of the same idea.
