1 bar = 100 kPa

1 kilopascal (kPa) = 0.145 pound-force per square inch (psi²) = 0.0102 kilogram-force per square centimeter (kgf/cm²) = 0.0098 atmospheres (atm)

1 pound-force per inch (psi) = 6.895 kilopascals (kPa) = 0.0703 kilogram-force per centimeter (kg/cm) = 0.0689 bar (bar) = 0.068 atmospheres (atm)

1 physical atmosphere (atm) = 101.325 kilopascals (kPa) = 14.696 pounds per square inch (psi) = 1.0333 bar (bar)

1 technical atmosphere = 98.0665 kPa

1 millimeter of water column (mmH2O) = 9.80665 pascals (Pa) 1 millimeter of mercury (mmHg) = 133.322 pascals (Pa)

1 Torr = 133.322 Pa, 1 dyn/cm = 0.1 Pa

How to use

This tool belongs to the “Calculators & converters” category.

1Type the value and check the unit the field is labelled with.
2Pick the target unit or formula; common equivalents are shown alongside.
3Round to the precision you need — results keep several significant decimals by default.

Any precision loss?

Decimal conversions of binary storage differ in the last digits. Use a proper maths package for engineering work.

Is data size 1000 or 1024?

Both conventions are shown; the difference is the KiB/KB and MB definitions.

Can I rely on the loan calculator?

It demonstrates the annuity formula only. Actual costs follow your bank or contract.
