  2. Change of base - Wikipedia

    en.wikipedia.org/wiki/Change_of_base

    In mathematics, change of base can mean any of several things: . Changing numeral bases, such as converting from base 2 to base 10 ().This is known as base conversion.; The logarithmic change-of-base formula, one of the logarithmic identities used frequently in algebra and calculus.

  3. Duodecimal - Wikipedia

    en.wikipedia.org/wiki/Duodecimal

    If the given number is in decimal and the target base is duodecimal, the method is same. Using the digit conversion tables: (decimal) 10,000 + 2,000 + 300 + 40 + 5 + 0.6 = (duodecimal) 5,954 + 1,1A8 + 210 + 34 + 5 + 0; 7249. To sum these partial products and recompose the number, the addition must be done with duodecimal rather than decimal ...

Also that time it takes for light to travel a distance of 299 792 458 metres. (SI base unit) shake ...

  5. Change of basis - Wikipedia

    en.wikipedia.org/wiki/Change_of_basis

    This change can be computed by substituting the "old" coordinates for their expressions in terms of the "new" coordinates. More precisely, if f(x) is the expression of the function in terms of the old coordinates, and if x = Ay is the change-of-base formula, then f(Ay) is the expression of the same function in terms of the new coordinates.

    The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [1]1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method.
