Happy Easter everybody- here it rains and thunders still!! While I don't understand, Bill , what it i all about, I like the 10 based usage. At least it sounds more 21st century. I appreciate all the zeros.
Now hopefully we will get rid of our foot and inch system , too, sometime. I have lived in this country since 1950 and still have trouble, I always change into the 10 system in my mind when I measure rugs and curtains and the like. Where I read feet I always divide by three which at least gives me a general feeling of meters, then I know where I am in my mind.
