x = 10/25.4 inches = 0.3937"
To take that from decimal to fraction, multiply by 8, 16, 32, or 64 (to get eights, sixteenths, thirty-seconds or sixty-fourths)
0.3937" = ~6.3/16" = ~12.6/32" = ~25.2/64"
I probably make it sound more difficult than it is, but it's simple algebra. So long as you know that 1" = 25.4mm, the rest is just simple math.
