3/8 X 32= 12
Fluorescent tubes are measured in 1/8ths of an inch. A T8 would be 8/8ths or one inch. Likewise a T12 would be 12/8ths or one and a half inches.
12/32 = 3/8
9/12
In fluorescent tubes the number represents the diameter of the tube. The tubes are measures in 1/8ths of an inch. T8 would be 8/8ths or 1 inch. T5 would be 5/8ths of an inch. Older fixtures took T12 which would be 12/8ths or 1.5 inches.
12 multiplied by 5/8 is 7 1/2 or 7.5
2/8 = 1/4 = 3/12
246.15 8ths
18.375 or 18 and 3 8ths
7 8ths = 7/8
There are two (2) 8ths in a quarter inch. This means that there are 8 8ths in a whole inch.
1 and 3/8ths is the same as 8/8ths + 3/8ths. This is summed to 11/8ths. Half of that would be 11/16ths.
