atm to Pa Converter - Standard Atmosphere to Pascal

Standard Atmosphere (atm) to Pascal (Pa)

Direct answer

1 atm = 101,325 Pa

Pa = atm × 101,325

Converter

Input

atm

Result

101,325Pa

Pa = atm × 101,325

atm = Pa × 0.000009869233

Example: 10 atm = 10 × 101,325 = 1,013,250 Pa.

Express both atm and Pa in the same base unit Pa (pascal), then cancel the shared base unit.

1
Rewrite atm in the base unit
$1 atm = 101, 325 Pa$
2
Rewrite Pa in the base unit
$1 Pa = 1 Pa$
3
Forward conversion
$1 atm = \frac{101 , 325 Pa}{1 Pa} \times 1 Pa = \frac{101 , 325}{1} Pa = 101, 325 Pa$
4
Reverse conversion
$1 Pa = \frac{1 Pa}{101 , 325 Pa} \times 1 atm = \frac{1}{101 , 325} atm = 0.000009869233 atm$

Guarded output

AI text is for interpretation only. The page calculator remains the source of truth for numeric results.

1 atm = 101,325 Pa.

10 atm = 1,013,250 Pa.

100 atm = 10,132,500 Pa.

Use Pa = atm × 101,325.

1 Pa = 0.000009869233 atm.

Use the conversion factor and round the result to the precision required by your calculation.
