UNDERSTAND THE UNITS

Converting pressure

Pressure is force per unit area. One pascal equals one newton per square metre. The standard atmosphere is defined as exactly 101,325 pascals.

How the calculation works

Multiply the source value by its base-unit factor, then divide by the destination factor. For example, 1 bar ≈ 14.50377377 psi.

Precision and rounding

Choose 6, 10 or 15 significant figures for the displayed result. Calculations use unrounded JavaScript numbers. The ≈ symbol indicates that displayed results may be rounded; significant figures are display precision, not measurement accuracy.
