Are material quantities exact?

No. The result is a planning estimate based on your measurements and assumptions. Confirm package coverage, material density, product instructions and job requirements with the supplier or contractor.

Can I use metric measurements?

Yes. The Home & DIY calculators support metric or imperial measurements where those units are relevant.
