Questions

How do I convert feet and inches to metres?+

Turn it into inches (12'6" is 150 inches), then multiply by 0.0254. 150 × 0.0254 = 3.81 m. One foot is exactly 0.3048 m.

How do I convert metres to feet and inches?+

Divide by 0.3048 to get feet: 3.81 m is 12.5 ft. The part after the point times 12 gives the inches: 0.5 × 12 = 6, so 12'6".

Can Planel read a drawing in feet and show it in metres?+

Yes. Each project keeps the unit its drawing was made in, and you can switch the sizes shown between feet and metres at any time.
