Crochet Hook Conversion Chart

I have had quite a few enquiries where customers are confused between Metric/US/UK crochet hook sizes and so I have put together this chart which I hope helps. It lists the Metric sizes and the US and UK equivalent as near as possible. Where it is marked N/A you will have to decide to go one up or one down and do a tension square to make sure the pattern works for you.
