    1 1/8 inches + 5 27/32 inches + 7 3/16 inches

    1/8 = 4/32
    3/16 = 6/32
    4 + 6 + 27 = 37
    37/32 = 1 5/32
    1 + 5 + 7 + 1 = 14
    Total: 14 5/32
    

    I wouldn’t call it chaos, it’s a straightforward algorithm:

    1. Identify the largest denominator
    2. Multiply each other fraction by [largest denominator divided by current fraction’s denominator] (e.g. 32/8 = 4, so 1/8 * 4/4 = 4/32)
    3. Determine the sum of every numerator
    4. Divide and simplify the number if necessary
    5. Determine the sum of the integers, including any integers added in the previous step

    This works for every measurement because the denominator is always a power of 2.

    With that said I absolutely prefer metric.

      In practice you would just use decimal inches. Doesn’t really make it better but you can machine something without ever seeing a fraction if you want to since everything will be in thousandths of an inch.

          most electronics breadboards and the pins from (non-tiny) microchips / ICs are spaced at 2.54mm apart, which i eventually realised is a tenth of an inch.

        Maybe in your particular industry, but I reckon most people using imperial units aren’t using measuring devices with decimal inches or needing the precision of .0001"
