Takeoff guides in metric, for Canadian drawings
CSA rebar, cubic metres, square metres and the Ontario code: the guides and free calculators we wrote for drawings drawn in Canada. Every page shows its arithmetic.
Concrete and rebar
Canadian rebar sizes: 10M to 55M
Diameter, area and kg per metre for every CSA bar, and the nearest US bar (a 15M is not a #5).
Concrete takeoff: footings, walls, slabs and rebar
Volumes in cubic metres, forms by contact area, and the Ontario code minimums to check.
How to read a footing schedule
Marks, sizes and reinforcing in metric and imperial, row by row.
Rebar weight calculator
CSA bars by the metre, the bar or the tonne.
Concrete calculator
Slabs, footings and walls in cubic metres or yards.
Drywall, studs and interiors
Drywall per square metre
Square metres per sheet, screws, tape and compound per m², with a worked example.
Drywall screws per square metre
The Ontario spacing rules as screws per sheet and per m².
Steel stud gauges and sizes
Gauge to mils and millimetres, sizes in inches and mm, studs and track per metre.
Drywall calculator

Metal stud calculator
