How to use this calculator
- Enter the value you want to convert.
- Choose the source and target units, then adjust the display precision if needed.
- Read the result. Select Convert to open a page for this value, or use the table below.
Definitions and assumptions
Pressure factors are expressed relative to pascals. A standard atmosphere is exactly 101325 Pa and one bar is exactly 100000 Pa. Liquid-column units use conventional reference values; actual pressure depends on density and gravity.
Frequently asked questions
how many kPa is 1 hPa?
1 Hectopascals = 0.1 Kilopascals. Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
how to convert hPa to kPa?
The calculator converts the input to the category's reference unit, then divides by the target unit's factor. 1 × 0.1 ≈ 0.1 Kilopascals. Use the source and target factors shown in the formula. The worked example uses the value on this page, and the table provides other common values.
Does this convert gauge pressure to absolute pressure?
The tool changes units only. Converting gauge pressure to absolute pressure also requires the reference atmospheric pressure, which must be added separately in consistent units.
Why is the displayed result rounded?
Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.
What input range can I use?
This calculator accepts non-negative values up to 1 trillion, with up to 8 decimal places. It does not calculate signed vectors or calendar date intervals.
Why is a unit unavailable?
A conversion is unavailable when a verified unit definition or a current exchange-rate value has not been configured. The tool does not invent a coefficient.
