I have often found this such a confusing topic, why do some countries use one and others use the other? I always wanted to know what fit with what. Do centimetres fit into yards or into metres and so on. I roughly know which measurements go together or translate but I still get confused. I have devised this helpful chart to help clear things up.
Most commonly used years ago was the imperial system, this was created by created by a British king and was commonly used all over the world. Many countries then moved over to using the metric system but America still used the imperial system to this day. The metric system is said to be easier to use as to get from millimetre to centimetres you multiply the number by 100 and again to get to metres and so on.
When shopping for fabric in the UK you can ask for 1/4 metre, 1/2 metre or 1 metre + measurements. Not all places will allow you to have the 1/4 metre of fabric but can always ask. In the USA you will buy your fabric by the yard and half yards.
