: If you wanted to convert measurements like 3 feet 2 inches you simply
: need to convert this to a common unit like inches (38 in this example)
: and use the conversion factor 25.4 (there are 25.4 mm per inch)

You don't have to use 25.4. If you want to scale a boat, this can be a handy
time to do so. When I built my hybrid Cormorant, I converted at 24mm to the
inch to give a low-volume boat. This was particularly easy since 1/16" goes
to 1.5mm, and those traditional plus and minus signs just add or subtract
half a millimetre (so 1/8+ would go to 3.5mm and 3/16- would go to 4mm).

: Once you have converted you will find you have a lot of decimal points but
: seeing as we are talking millimetres we dont need that level of accuracy,
: so

You always want accuracy. What you are talking about here is precision, a
very different thing, all too frequently (as opposed to regularly) confused !
