Calculator which converts units of pressure

This calculator calculates the height or altitude difference between two points using barometric formula or barometric leveling method.

This online calculator calculates the boiling temperature of water based on the atmospheric pressure in millimeters of mercury or the altitude above the sea level.

This calculator uses barometric formula to find out the pressure at the given altitude

This calculator computes the buoyant force and weight of the liquid displaced, given the volume of a body in water

This online calculator computes pressure, cause by given mass over given surface in gravity field. Result is displayed using different units of pressure

This online calculator computes saturation vapor pressure for a given temperature and atmospheric (barometric) pressure

The first calculator converts relative humidity to absolute humidity for a given temperature and barometric pressure. The second calculator does the opposite - converts absolute humidity to relative humidity for a given temperature and barometric pressure. Some theory and formulas can be found below the calculator.
