The value of sackurTetrode is at T = 1 K and p = 101.325 kPa. We set up the conversion as follows: 18 ms × 1 s 1, 000 ms 0.018s The conversion factor’s numerical values do not affect our determination of the number of significant figures in the final answer. Note that the values of loschmidt and molarVolume are at T = 273.15 K and p = 101.325 kPa. Math.js includes the following physical constants. They can be used with units bits ( b) and bytes ( B). The following binary prefixes are available. The following decimal prefixes are available. Surface and volume units can alternatively be expressed in terms of length units raised to a power, for example 100 in^2 instead of 100 sqin. Note that all relevant units can also be written in plural form, for example 5 meters instead of 5 meter or 10 seconds instead of 10 second. Note: all time units are based on the Julian year, with one month being 1/12th of a Julian year, a year being one Julian year, a decade being 10 Julian years, a century being 100, and a millennium being 1000.

These can be used via the Unit object, or via math.evaluate(). This section lists all available units, prefixes, and physical constants. Get the string name of the current type of the value of this Unit object, e.g. The function willĭetermine the best fitting prefix for the unit. Works with units with or without a value. Other quantities can be expressed as a multiple of the unit. Returns a clone of a unit represented in SI units. Unit Converters Full Versions A unit is a measurement of a quantity that is defined or adopted by tradition or law. All Weight and Mass Conversions Nearly 200 different weight and mass units. Such as pounds, ounces, grams, kilograms, etc. Common Weight and Mass Conversions A few of the more common weight and mass units. The type of the returned value depends on how the unit was created andĬan be number, Fraction, or BigNumber. Choose which conversion page you wish to use. The type of the returned value is always number. Specified unit (a unit with optional prefix but without value). Get the value of a unit when converted to the Online converters and unit conversions for Acceleration, Angular Units, Area, Computer Storage, Decimals, Fractions, Density, Distance/ Length, Energy, Work, Force. Used when serializing a unit, see Serialization. For example, if we were defining fahrenheit for the first time, we would use: math.createUnit('fahrenheit'. This is very helpful for temperature scales that do not share a zero with the absolute temperature scale. offset A value applied when converting to the unit.Possible values are 'none', 'short', 'long', 'binary_short', or 'binary_long'. prefixes A string indicating which prefixes math.js should use with the new unit.definition A string or Unit which defines the user-defined unit in terms of existing built-in or user-defined units.The second argument to createUnit can also be a configuration object consisting of the following properties: evaluate ( ' 8 foo * 4 feet ' ) // 32 foo feet A 'foo' cannot be expressed in terms of any other unit.
