# A unit converter you don't have to click through

Written 18 October 2026 by Adrian Viziteu. Every example was run through Ratio 0.6.4 that day. Results are rounded to 2 decimals.

Most converters make you pick a category, then a unit, then another unit. In Ratio, you just type the conversion as a sentence, with `in` or `to`. Then keep calculating with the result.
