A standard atmosphere is a pressure unit defined as exactly 101,325 pascals.
The atmosphere unit became useful as a reference for average sea-level air pressure in science and education.
atm is used in chemistry, gas laws, diving references, laboratory work, classroom problems, and pressure comparisons.
A pascal is the SI pressure unit equal to one newton per square meter.
The pascal became the standard SI pressure unit for scientific, engineering, and technical measurement.
Pa is used in sensors, formulas, simulations, laboratory data, fluid mechanics, acoustics, ventilation, and material testing.
Mathematically, pascal (Pa) = standard atmosphere (atm) converted with the formula below.
1 atm = 101,325 Pa
1 Pa = 0.00001 atm
Formula: value × 101325
Example: 15 atm = 1,519,875 Pa
Precision note: Use exactly 101,325 Pa per atm. Preserve decimal atm values before multiplying.
1 atm = 101,325 Pa
1 Pa = 0.00001 atm
| Standard atmosphere [atm] | Pascal [Pa] |
|---|---|
| 0.01 atm | 1,013.25 Pa |
| 0.1 atm | 10,132.5 Pa |
| 1 atm | 101,325 Pa |
| 2 atm | 202,650 Pa |
| 5 atm | 506,625 Pa |
| 10 atm | 1,013,250 Pa |
| 20 atm | 2,026,500 Pa |
| 50 atm | 5,066,250 Pa |
| 100 atm | 10,132,500 Pa |
One standard atmosphere equals exactly 101,325 Pa.
2 atm equals 202,650 Pa.
No. Standard atmosphere is a fixed reference, not a live weather measurement.
