About this tool
Convert atmospheres to pascals instantly. Free, bidirectional, and fully in-browser.
1 atmosphere equals 101325 pascals — enter any atmosphere value to convert it to pascals instantly. This Atmosphere to Pascal converter is a client-side tool: it applies a single multiplication (Pa = atm × 101325) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert pascals back to atmospheres. A reference table lists common atmosphere values already converted, and nothing you enter is sent to a server.
Open Atmosphere to Pascal Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Atmosphere field.
Read the equivalent in pascals in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert pascals to atmospheres.
The result updates as you type, and the swap button flips the conversion to pascal → atmosphere without reloading.
The conversion uses the precise factor (Pa = atm × 101325), 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 101325 pascals. Multiply the atmosphere value by 101325 to convert. For example, 10 atm = 1013250 Pa.
Pa = atm × 101325. This tool applies it automatically and shows a worked example: 10 atm = 1013250 Pa.
Yes. Press the swap button, or type into the pascal field, and the tool converts pascals to atmospheres using the inverse of the same relationship.
It uses the standard pressure definition (Pa = atm × 101325), 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.
