Chemistry often uses two types of logarithms, common logarithms (or Briggian) and natural logarithms (or Napierian). The power to which a base of 10 must be elevated in order to obtain a number is called the number’s common logarithm (log). It is harder to work with trigonometric functions, but individuals seem to be more familiar with them than logarithms.
As also occurs in astronomy or integrated circuits, it is usually used when numbers are too high or too small to tackle quickly. When compressed, using an inverse operator known as “antilog”, a number can be transformed back to its original form.
