|Pressure units converter
Calculator which converts units of pressure
|Altitude difference by barometric formula
This calculator calculates the height or altitude difference between two points using barometric formula or barometric leveling method.
|Altitude Boiling Point Calculator
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.
|Altitude Pressure Calculator
Calculate the pressure at a given altitude using the barometric formula. Adjust the sea level pressure, temperature, and altitude to obtain the altitude pressure value.
|Buoyant Force Calculator - Weight of Displaced Liquid
This online tool allows you to calculate the buoyant force and weight of the liquid displaced by a submerged object in water.
|Gravity Pressure Calculator
This online calculator computes pressure caused by a given mass over a given surface in a gravity field.
|Saturation vapor pressure
This online calculator computes saturation vapor pressure for a given temperature and atmospheric (barometric) pressure
|Relative humidity to absolute humidity and vice versa calculators
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.
|Density of oil
Recalculation of the density of oil for different temperature and pressure values. Formulas are taken from Russia's GOST R 8.610-2004. "State system for ensuring the uniformity of measurements for the density of oil. The tables for recalculation" standard
|Clapeyron-Mendeleev equation. The relationship between the number of moles of gas, the temperature, volume and pressure.
Clapeyron-Mendeleev equation. The relationship between the number of moles of gas, the temperature, volume and pressure.
|Volume of body given the buoyant force
This calculator computes the volume of body given the buoyant force and density of the body, assuming that the buoyant force equals gravity force.
This online calculator can solve hydrostatic pressure problems by finding unknown values in the hydrostatic equation.
Barlow´s Formula is used to calculate the pipe pressure considering its diameter, wall thickness, and hoop stress (in the pipe material).
