How to use commas and decimal points in numbers
The English reverse the use of commas (,) and decimal points (.) in numbers compared to Dutch. In Dutch, a period means multiples of thousand. So, a Dutch person would write ‘2.200 jaar oud’, while in English you would write ‘2,200 years old’. The opposite exists as well: Dutch uses a comma, where English uses a decimal point. ‘7.5 million’ in English, pronounced as seven point eight million, means the same as ‘7,5 miljoen’ in Dutch.
