A logarithmic unit is a unit that can be used to express a quantity (physical or mathematical) on a logarithmic scale, that is, as being proportional to the value of a logarithm function applied to the ratio of the quantity and a reference quantity of the same type. The choice of unit generally indicates the type of quantity and the base of the ...

Logarithmic can refer to: Logarithm , a transcendental function in mathematics Logarithmic scale , the use of the logarithmic function to describe measurements
Edmund Gunter of Oxford developed a calculating device with a single logarithmic scale; with additional measuring tools it could be used to multiply and divide. The first description of this scale was published in Paris in 1624 by Edmund Wingate (c.1593–1656), an English mathematician, in a book entitled L'usage de la reigle de proportion en ...
In mathematics, the logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number.For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the 3 rd power: 1000 = 10 3 = 10 × 10 × 10.
A log semiring has the usual Euclidean metric, which corresponds to the logarithmic scale on the positive real numbers. Similarly, a log semiring has the usual Lebesgue measure , which is an invariant measure with respect to log multiplication (usual addition, geometrically translation) with corresponds to the logarithmic measure on the ...
In 1620 Edmund Gunter developed a ruler with a logarithmic scale; with a pair of dividers it could be used to multiply and divide. [8] In c. 1622, William Oughtred combined two handheld Gunter rules to make a calculating device that was essentially the first slide rule .
