How to write a percent: language and country-specific tables
Percents are written differently in different parts of the world and in different languages. The writing style can be, for example, '75.6%', '75,6%', '75.6 %', '75,6 %' or even '%75.6'. See the writing rules in the tables that list almost all countries and languages in the world.

Decimal separator and thousand separator
In English-speaking countries, a dot is used as a decimal separator. The European custom is to use a comma. A dot, comma, or space are used as thousand separators in different parts of the world. See the table for the practices of each country.

Percent sign and space: 50% is English, 50 % is European
There is no space between the percent sign (%) and the number in English language. In other European languages there is. However, it is common to leave the space out.

Inverse proportionality
In inverse proportionality, as the value of one variable increases, the value of the other variable decreases in the same proportion. This can be applied to calculating speed and time, area calculations, resource allocation, calculating the number of employees, and many other practical matters. You can use the calculator on this website to calculate calculations based on inverse proportionality.

Direct Proportionality
In direct proportionality, the relationship between two variables remains the same. This can be applied to pricing, estimating distance and time, image size changes, and many other practical matters. The calculator on the page makes it easy to perform calculations based on direct proportionality.

Percentage calculations without a calculator
Percentage calculations become much easier when we understand that they are multiplication calculations. You can put the numbers to be calculated in a different order. You can also separate the tens and hundreds into their own numbers.

Negative percent
A percentage calculation can easily result in a negative percentage instead of a positive percentage. You can also calculate a percentage from a negative number. The calculation gets a bit strange when you calculate the percentage change using a negative number, but that's not impossible either.

Percentage and percentage point
A percentage means a hundredth and they are used to measure a share of something. The percentage point, on the other hand, is used when comparing percentages to each other or when referring to percentages of certain percentages.
