Re: glass scales for atlas 12" lathe #3986

No, 25.4 is exact since July of 1959..? Prior to that time, the US inch was about 0.000002¡± longer and the English inch was about 0.0000017¡± shorter.? That is 2 microinches and 1.7 microinches respectively. ? So to convert inches to millitetres multiply by 25.400000.? To convert millimeters to inches, divide by 25.400000.? Or you can divide or multiply by 0.0.93700787042.? Most people will find 25.4 easier to remember.? ? ?
