How many atm is 21 bar?
Answer
21 bar ≈ 20.73 atm
Same pressure: 21 bar = 2,100 kPa; 21 bar ≈ 304.58 psi; 21 bar ≈ 21.41 kgf/cm². atm is the standard atmosphere (101,325 Pa); the technical atmosphere (at) is 1 kgf/cm².
21 bar ÷ 1.01325 ≈ 20.73 atm

What is the formula to convert bar to atm?
Divide the pressure in bar by 1.01325, the exact number of bar in one standard atmosphere: atm = bar ÷ 1.01325. For this page: 21 bar ÷ 1.01325 ≈ 20.73 atm.
What is 21 bar in kPa, psi and kgf/cm²?
The same pressure is 2,100 kPa, about 304.58 psi, or about 21.41 kgf/cm². Gauges print bar, psi, kPa or kgf/cm²; textbooks print atmospheres.
How do I convert 20.73 atm back to bar?
Multiply by 1.01325: 20.73 atm × 1.01325 ≈ 21 bar.
