Convert Kilopascals to Baryes

Formula

Ba = kPa × 10000

Derivation from SI units:

• 1 kPa = 10³ Pa
• 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
• 1 kPa = 1000 Pa ÷ 0.1 Pa per Ba = 10000 Ba

Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; Barye definition: barye.

Worked examples

1. A reading of 20 kPa converts to 200000 Ba.
   20 kPa × 10000 = 200000 Ba
2. A value of 300 kPa is 3000000 Ba.
   300 kPa × 10000 = 3000000 Ba

Where it's used

Kilopascals are used for tyre pressure outside the United States (about 200–250 kPa for cars), while baryes appear in older physics and acoustics literature. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
