One atmosphere equals approximately 1.01325 bar. The two units are nearly identical in magnitude, making rough conversions easy.
Multiply the atmosphere value by 1.01325. For example, 3.5 atm × 1.01325 = 3.546 bar.
The bar was originally defined as 10^6 dynes per cm^2, which happens to be very close to atmospheric pressure. One atmosphere is 1.01325 bar, just 1.3% more than 1 bar.
Bar is widely used in industry, tire pressure (in Europe), and meteorology. The atmosphere is common in chemistry and physics for defining standard conditions (STP).
