Conversion table

Every inch from one to twenty-four, in centimetres. One inch is 2.54 cm exactly, which is not a measured approximation but a definition: the international yard was fixed at 0.9144 metres in 1959, and the inch follows from it. Every row below is that constant multiplied out.
The table stops at twenty-four because two feet covers most of what people measure by hand: paper, screens, shelves, timber offcuts. Change Rows for a longer one, or Step to 0.5 or 0.25 if you work in halves and quarters rather than whole inches.
It prints on one page on purpose. If you want centimetres down the left instead, the centimetres to inches chart is the same table the other way round.
How to use it
- Read the table, which is built for this pair of units when the page opens.
- Change Start, Step or Rows to cover a different range.
- Press Print for the table on its own, without the rest of the page.
Questions
How many cm is one inch?
2.54 centimetres, exactly. It is a definition rather than a measurement: since 1959 the international inch has been defined as 25.4 millimetres, so the figure never rounds and never changes. Multiply by 2.54 to go from inches to centimetres and divide by it to come back.
Does the chart print on one page?
Yes, that is what the Print button is for. The page prints the table and the heading and leaves out the navigation, the search box and the ads, so a chart pinned above a workbench is the chart and nothing else.
Can I get half and quarter inches?
Set Step to 0.5 or 0.25 and the rows follow. Twenty-four rows at a quarter-inch step covers six inches, so raise the row count to match the range you want. Both boxes update the table as you type.
Can I change the range of the chart?
Yes. Start is the first value in the left column, Step is the gap between rows, and Rows is how many there are, up to two hundred. All three update the table as you type, and the unit menus above them will convert any other pair in the same category.
Is the table built on my device?
Yes, by WebAssembly compiled from Rust, using conversion factors that are compiled in rather than fetched. Nothing is uploaded, nothing is stored, and the page prints the same table with the network off.

Everything above runs inside your browser as WebAssembly compiled from Rust. Nothing you type is uploaded, logged or stored on a server. You can load this page once, go offline, and it still works.
This page makes no requests at all, to anywhere. That is not a promise in the copy: it is a Content-Security-Policy header your browser enforces, and connect-src on it is none. Open the network tab and watch nothing happen.
