how it works

Write the math. The units work themselves out.

01
Multiply and divide
Units combine with the numbers, cancel, and simplify on their own.
F = 2.5 kg × (4 ms)²2 × 0.5 m = 40 N
02
Add and subtract
Compatible units line up, even when they are written differently.
12 ms + 36 kmh = 22 ms
03
Catch mistakes
Quantities that can't mix are flagged the moment you type them.
6 N·m2 s + 4 kg ✗ power and mass can’t be added
04
Convert to anything
Click a unit to switch it. Yes, even furlongs per fortnight. I hate you if you use these units.
60 mih = 161,280 furlongfortnight

three canvases

One sheet, three ways to look at it.

Explore canvases

Pageless

A free canvas. Drop lines anywhere and let the sheet grow with your thinking.

Paper

A real page on a desk. Lines flow top to bottom, laid out and ready to print.

Node

See the same sheet as cards and connections, so you can follow what depends on what.

units.engine

Everything the engine checks.

See every capability

Units are first-class

SI, US customary, temperatures and compound engineering units, written the way you would on paper.

Change units in place

Click a unit to convert it. The physical quantity stays the same everywhere.

Catch bad dimensions

Incompatible dimensions are reported before an error can spread.

Live formulas

Change one value and everything that depends on it updates.

Standards by default

Domain profiles give ambiguous symbols the meaning your discipline expects.

Work together live

Share a sheet and see each other's cursors and edits in real time.
