Centimeters to Feet Conversion

Hi,

Quite often I come across a plan that is using meters and centimeters as the means of calulation. Being an ignorant American whose school system refused to follow the world's lead of the metric system, I have borrowed a formula for a quick and easy conversion.

The Formula

cm (centimeters) divided by 2.54 = in (inches)

For Example:

35.433 inches/ 12 inches (foot) = 2.9527

To convert the centimeters directly to feet let's take 2.54 x 12 = 30.48

90 cm/30.48 = 2.9527 ft

Missed the most important part after For Example:

90 cm/ 2.54 = 35.433 inches

Re: Centimeters to Feet Conversion

One nice thing, though, is the SH3D will do the conversion for you. Used a US drawing as inspiration for part of a plan. Simply changed my preferences, drew up the plan in US measures, changed preferences and there were all the cm measurements (which had to be tweaked to comply with local building standards, but still).

Curiously, while the feet unit is generally abandoned in Europe, boat lengths are still commonly specified in feet (but not draught/beam). And in terms of building, by the way, you may find that the rule of 2,54 cm = 1 inch does not always apply.

  • Construction beams are still, in places, referred to in inches (thumbs). For instance, a builder might suggest using two-by-four beams (2"×4" / to-tom-fire). But if even if sometimes called two-by-fours, the beams will actually be cut to metric standards (here cut 50mm×100mm and adjusted to 48mm×96mm).
  • To add to the confusion, if you like some SH3D users work with plans from archives to rebuild old houses, beware that the old foot/inch units have not always been the same and different standards were used in different places - as shown in a Wikipedia scan.
