About this tool
Convert atmospheres to kilopascals instantly. Free, bidirectional, and fully in-browser.
1 atmosphere equals 101.325 kilopascals — enter any atmosphere value to convert it to kilopascals instantly. This Atmosphere to Kilopascal converter is a client-side tool: it applies a single multiplication (kPa = atm × 101.325) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert kilopascals back to atmospheres. A reference table lists common atmosphere values already converted, and nothing you enter is sent to a server.
Open Atmosphere to Kilopascal Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Atmosphere field.
Read the equivalent in kilopascals in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert kilopascals to atmospheres.
The result updates as you type, and the swap button flips the conversion to kilopascal → atmosphere without reloading.
The conversion uses the precise factor (kPa = atm × 101.325), 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.
One atmosphere is 101.325 kilopascals. Multiply the atmosphere value by 101.325 to convert. For example, 10 atm = 1013.25 kPa.
kPa = atm × 101.325. This tool applies it automatically and shows a worked example: 10 atm = 1013.25 kPa.
Yes. Press the swap button, or type into the kilopascal field, and the tool converts kilopascals to atmospheres using the inverse of the same relationship.
It uses the standard pressure definition (kPa = atm × 101.325), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
