Thanks, I’ll be using that one.
I can’t remember who passed it along to me, but I used it all the time when I lived in France. Still pull it out from time to time.
There’s also converters on there for just about any other measurement you can dream up – some pretty hardcore geekery, but even as a semi-geek, I appreciate how hard someone has worked to put all those conversions in one place and organize them logically.
