Convert bar to petapascal
Please provide values below to convert bar [bar] to petapascal [PPa], or Convert petapascal to bar.
1 bar = 1.0000e-10 PPa. To convert bar to petapascal, multiply the value by 1.0000e-10; to go the other way, divide by it (1 PPa = 10000000000 bar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 bar = 1.0000e-10 PPa
- 1 PPa = 10000000000 bar
- 10 bar = 1e-09 PPa
- 100 bar = 1e-08 PPa
How to Convert Bar to Petapascal
1 bar = 1e-10 PPa
Example: convert 15 bar to PPa:
15 bar = 15 × 1e-10 PPa = 1.5e-09 PPa

Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
Petapascal
A petapascal (PPa) is a unit of pressure equal to 10^15 pascals.
History/Origin
The petapascal was introduced as part of the SI prefix system to represent extremely high pressures, mainly in scientific and industrial contexts, as the need to measure such large values arose with advancements in high-pressure physics and astrophysics.
Current Use
Petapascal is used in fields such as astrophysics, geophysics, and high-pressure physics to quantify extremely high pressures, such as those found in planetary interiors or during high-energy experiments.
Frequently Asked Questions
What is 1 bar in petapascal?
1 bar (bar) = 1.0000e-10 petapascal (PPa).
How do you convert bar to petapascal?
Multiply the bar value by 1.0000e-10. For example, 25 bar × 1.0000e-10 = 2.5e-09 PPa.
What is 10 bar in petapascal?
10 bar = 1e-09 PPa.
Which unit is larger, the bar or the petapascal?
The petapascal is the larger unit: 1 bar equals only 1.0000e-10 PPa.
