Formula
How this calculation works
Ratio units use conversion factors; temperatures use scale and offset; currencies use current rates

- 2
For physical units, Numy converts through a shared base unit.
- 3
Currency conversions use the rate status and date shown in the calculator.
Keep the calculation, not just the answer
Numy lets you write each step on its own line, change values later, keep running totals, convert units, and return to calculations from history.
02 / CHECK
Keep the expression visible
The answer stays beside the expression so you can verify the inputs at a glance.
03 / CONTINUE
Move the complete work into Numy
Use the app when you want multiple lines, history, variables, and reusable notes.
