A pascal is the SI pressure unit equal to one newton per square meter.
The pascal became the standard SI pressure unit for science, engineering, instrumentation, and technical reporting.
Pa is used in sensors, laboratory measurements, engineering calculations, ventilation, acoustics, fluid mechanics, and material testing.
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 scientific and educational contexts.
atm is used in chemistry, gas laws, diving references, laboratory work, classroom problems, and pressure comparisons.
Mathematically, standard atmosphere (atm) = pascal (Pa) converted with the formula below.
1 Pa = 0.00001 atm
1 atm = 101,325 Pa
Formula: value × 0.00000986923266716
Example: 15 Pa = 0.000148 atm
Precision note: Use exactly 101,325 Pa per standard atmosphere. Keep decimals when comparing pressures that are near but not equal to one atmosphere.
1 Pa = 0.00001 atm
1 atm = 101,325 Pa
