Understanding your result
The converted value describes the same pressure quantity in the selected target unit. Display rounding does not add precision to the original measurement.
Common mistakes
- Confusing the source and target units, or overlooking a prefix or case-sensitive symbol.
- Expecting a unit conversion to change gauge pressure into absolute pressure.
Check your calculation
- Convert to the target unit and then reverse the direction. Within display rounding, you should recover the original value.

How do I convert kilopascals to conventional inches of mercury?
Enter the value in kilopascals to find the same pressure quantity in conventional inches of mercury. The number changes to match the unit; the underlying quantity stays the same. Check the definitions below when a unit has more than one convention.
Common uses
- Interpret pressure specifications in a familiar unit.
- Compare pressure readings using consistent conventions.
How it works
For the displayed direction, 1 kPa equals 0.29529983301 inHg (0 °C). The engine converts through the shared pressure base quantity. Atmospheres are standard atmospheres. Mercury-column factors use the conventional 0 °C definition; torr is 1/760 of a standard atmosphere. The multiplier is derived from the two centralized unit factors. Keep full precision until the final result; displayed answers use up to 12 significant digits.
Worked example
10 kPa converts to 2.9529983301 inHg (0 °C). For the reverse direction, swap the units and enter 2.9529983301 inHg (0 °C); the result is approximately 10 kPa.
