Anxiety no, resenting having to punch in more numbers to get the correct answer yes. When one spends hours at a time standing up programing a machine on the shop floor extra key punches add up. Add to that editing a program in metric that isn't going as planned is a true pain. I realize most do not have to use dimensions as small as .0001 or .00254 in metric but to act as if an extra number and 3 different numbers is immaterial when calculating angles/ radius or even simple addition and subtraction is very flippant. Try it sometime. I can add and subtract .0001 without a calculator but multiples of the metric equivalent require a calculator.
