About this calculator

This calculator is just a basic tool made to easily figure out the volume or mass of hydrogen at pressure.
Boyle's law is fine and dandy until the pressures get higher and start to deviate from the actual value.

The base calculation comes from the paper, "Revised Standardized Equation for Hydrogen Gas Densities for Fuel Consumption Applications" (link) by Eric W. Lemmon, Marcia L. Huber (National Institute of Standards and Technology), and Jacob W. Leachman (University of Wisconsin-Madison Cryogenics Lab); published in the Journal of Research of the National Institute of Standards and Technology, dated July 22, 2008.
Calculation simplified in order to be able to calculate mass, volume, pressure, or temperature using various units. I wasn't able to solve the equations to get temperature or pressure as the solution.
