These tables contain 188 values for the Universal Gas Constant in the most likely combinations of units. These include the most commonly used values for the universal gas constant when working in metric units, SI units, English engineering units and US customary units.

R = P×V ⁄ T. The value will change for different units. But universally it will remain the same for the ideal gas at any pressure, temperature or volume. The table shows universal gas constant value for different units.

The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant , expressed in units of energy per temperature increment per amount of substance , rather than energy per temperature increment per particle .

2021年2月11日 · The gas constant (R) is a proportionality constant used in the ideal gas law and Nernst equation. It’s also called the ideal gas constant, universal gas constant, or molar gas constant. Basically, the gas constant is the same as the Boltzmann constant (k), except the gas constant includes Avogadro’s number (N A): R = NA k

The induvidual gas constant, R, for a gas can be calculated from the universal gas constant, R u ( given in several units below), and the gas molecular weight, M gas : R = R u / M gas (1)

The gas constant, R. A value for R will be given you if you need it, or you can look it up in a data source. The SI value for R is 8.31441 J K-1 mol-1.

R是个系数，应该是代入计算的时候做换算，而不是直接换算吧！ 当P的单位为KPa V的单位为L 那么R是8.314L·KPa/mol/k为什么当P单位变成Pa V的单位仍然为L R就是0.008314…

(3.23) while for other units, R can be calculated from the relation R 10.73146 p unit psia °R T unit V unit ft3 lbm m unit. . . . . . . . . (3.24) For example, the ...

gas constant: constant derived from the ideal gas equation, PV = nRT. R = 8.314 L kPa/mol K.

2025年1月9日 · R value for kPa is a crucial physical property used in engineering calculations. It represents the gas constant, which relates pressure, volume, and temperature for a particular gas. R value is expressed in kiloPascals per Kelvin (kPa/K) …
