Conversion Tables

Sometimes the useful thing is not one answer but the whole chart: every inch from one to twenty-four in centimetres, oven temperatures in five degree steps, or the pound weights across a baby's first year. Pick a pair of units and a range and the table is generated here, ready to print or to keep open in a tab.

It prints on one page on purpose, without the navigation, the footer or anything else that would waste the paper, because a printed conversion chart on a kitchen wall or a workshop bench is still the fastest lookup there is when your hands are full.

The same conversion engine is behind this as behind the unit converter, so a value in the table matches what the converter gives for the same pair, and both go through the SI base unit rather than through rounded factors copied from somewhere else.

Common tables people come here for: inches to centimetres for screens and paper, Celsius to Fahrenheit for ovens and weather, kilograms to pounds and stones for body weight, millilitres to fluid ounces and cups for recipes, and kilometres to miles for running distances.

How to use it

Choose the category and the two units.
Set the start, step and number of rows.
Print the page, or copy the table into a document.

Questions

Can I print this?

Yes. The table prints as-is, with the page furniture stripped away by the browser's print view.

Which conversion factors are used?

Exact definitions wherever one exists (1 inch is exactly 25.4 mm, 1 pound is exactly 0.45359237 kg), with double-precision arithmetic for the rest.

Does it print without the rest of the page?

Yes. The print stylesheet drops the header, the footer, the navigation and the explanation, leaving the table and its heading, so a chart comes out on one sheet with nothing wasted around it.

Can I choose the step between rows?

Yes, along with the start and the end. Whole numbers suit lengths and weights; a step of five suits oven temperatures; a step of a quarter suits recipe measures. The table redraws as you change them.

Are the numbers rounded?

They are displayed to a sensible number of decimals for the size of the value, while the conversion itself is done at full precision. Nothing is rounded twice, so a value in the table matches the unit converter to the digits shown.

Why does my table start where it does?

Because it starts at whatever is in the Start at box and adds the Step for each row, so the defaults give you 1 to 25 in ones. Nothing is snapped to a tidier number behind your back. Set the start explicitly when the table has to begin somewhere particular, such as a chart of oven temperatures or body weights.

Ready-made charts

The pairs looked up most often have a chart each, built when the page opens and ready to print:
