The popularity of the Internet allows you to chat and visit message forums with people from many different countries. This causes minor difficulties while chatting as some countries use traditional units such as feet, pounds, and Fahrenheit, while other countries use the metric system with meters, kilograms, and Celsius.

I have gathered together all the basic conversions you may need for these international conversations. Hopefully it will make it easier for everyone by keeping them all in one place.
