Unit Converter
Reckonersweight 1reckoner · computes, doesn't store
The recipe is in cups, the plank is in inches, and the weather report from your cousin is in Fahrenheit. The Unit Converter turns one unit into another and hands you the number, no history kept, no questions asked. It is the kitchen-drawer calculator for a world that never quite agreed on measurements.
This is not a screenshot. It's the real tool, running right here — go on, put something in it.

Questions people ask
Does this unit converter work offline?
Yes — it is a single HTML file that runs entirely in your browser, no connection needed. It computes your conversion on the spot and stores nothing; nothing you type ever leaves the page.
How do I convert between units with it?
You give it a value and the units on each end, and it gives you the answer. There is a live demo right on the page — go on, try it, it is the real thing.
Who needs an offline unit converter?
Cooks with foreign recipes, travellers with foreign speedometers, woodworkers with old plans, and anyone whose phone signal disappears exactly when the measurements matter.
Fits your knife at weight 1. Nothing here is final — Knife follows Life. Reforging within your tier is free, forever. Add it, drop it, reforge later; the file stays yours either way.
