In the times that I use metric and inches I just "round" 25 mm to the
inch,
4" ~ 100mm.
1/2 inch ~ 12.5 mm or 6 1/2 mm
1/4 inch ~ 6.25mm or 6 1/4 mm
1/8 inch ~ 3.125mm or 3 1/8 mm

When you get down to it as far as I'm concerned, it's all what sounds
better. I've got to tell you, 75° F sounds a whole lot warmer than 24°C. The
older I get, the colder it seems to get.
