Decimal inches multiplied by 25.4 = approximate mm. N.B. When
specifying metric sheet or trim sizes, fractional approximate mm measurements
must be rounded off to the nearest whole number; i.e., 50.8 mm
is not a practical measurement; it should be rounded up to 51 mm,
and 0.5 mm is always rounded down.
Measure twice - cut once. ;-)
Good Lord, honeybear! Are you a rocket scientist, or sumthin? LOL.....
Seriously, loddy, thank ya, you sweet thang you.....my Dad is neither a rocket scientist, or neurosurgeon......he merely needs some sort of 'jumpring' [glorified name for an 'o' ring, if you ask me] that using inches is 1/4" in diameter....he makes earrings out of some of the fishing flies that he makes....
Thank you again.
