Your first calculation, step by step

Before you start

You do not need an account for any of this. Have your numbers ready, and note the unit each one is in, for example kilograms, centimetres or rupees. If you are unsure which calculator you want, a quick search by name is enough to start.

The steps

1. 1Select Search in the header, or press Ctrl K (⌘ K on a Mac), and type what you want to calculate.
2. 2Choose a result to open the calculator page.
3. 3Fill in the fields on the inputs side. Read the label and unit beside each one.
4. 4Watch the answer, which updates straight away as you enter values.
5. 5Read the labelled result. Press Copy result if you want to paste it elsewhere.
