About this tool
Convert rems to CSS inches instantly. Free, bidirectional, and fully in-browser.
1 rem equals 0.1666666667 CSS inches — enter any rem value to convert it to CSS inches instantly. This Rem to CSS inch converter is a client-side tool: it applies a single multiplication (in = rem × 0.1666666667) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert CSS inches back to rems. A reference table lists common rem values already converted, and nothing you enter is sent to a server.
Open Rem to CSS inch Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Rem field.
Read the equivalent in CSS inches in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert CSS inches to rems.
The result updates as you type, and the swap button flips the conversion to css inch → rem without reloading.
The conversion uses the precise factor (in = rem × 0.1666666667), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
