# Permille Converter

A permille is a unit of measurement used to express ratios in parts per thousand. It is denoted by the symbol ‰, which is similar to a percent sign (%) except that it represents one-tenth of a percent. A decimal, on the other hand, is a base-10 numeral system that uses ten digits (0-9) to represent numbers. Converting permille to decimal is a simple process that involves multiplying the permille value by 0.001.

To convert permille to decimal, simply take the permille value and multiply it by 0.001. For example, if you have a permille value of 500, you can convert it to decimal as follows:

500 x 0.001 = 0.5

Conversely, to convert decimal to permille, you need to multiply the decimal value by 1000. For example, if you have a decimal value of 0.75, you can convert it to permille as follows:

0.75 x 1000 = 750 ‰

It's important to note that permille is rarely used in everyday situations and is mainly used in scientific and industrial contexts. However, if you do come across permille values, converting them to decimal is a straightforward process that can be easily accomplished with the help of an online converter.

To convert a decimal to a permille, simple multiply the decimal by 1000.
