Solve pressure, volume, temperature, or moles with the Ideal Gas Law (PV=nRT) or Combined Gas Law; also gas density and molar mass.
gas-law-calculatorAstronomy
Convert astronomical positions between equatorial (RA/Dec J2000 and B1950), galactic (l/b), and supergalactic (SGL/SGB) coordinate systems. Accurate J2000 IAU 1958 galactic rotation, de Vaucouleurs supergalactic system, and IAU 1976 precession between epochs. Accepts sexagesimal (12h51m26s) or decimal-degree input and shows all four systems for each object.
