In many applications, the density of hydrogen under "extreme" conditions must be calculated. This calculator enables determining the mass or density of hydrogen under pressure.
The following tool processes the inputs "Temperature", "Pressure" and "Volume". Real gas conditions are applied, so accurate values can be obtained even at high pressures.

Der nicht-lineare Dichteverlauf ist z.B. dafür verantwortlich, dass in ein 700-bar-Fahrzeug nur etwa 70% mehr Wasserstoff hinein passt als in ein 350-bar-Fahrzeug — obwohl der Druck doppelt so hoch ist.
All online tools have been programmed to the best of my knowledge; however, errors cannot be entirely excluded. Any use is therefore at your own risk. Any legal or financial claims are excluded.
