Calculator & tools
Lumber calculators
Four tools for the arithmetic this trade does all day: totalling a tally, working a price back and forth between MBF and cubic metres, converting quantities, and sizing a span.
They are free, they need no sign-in, and they run entirely in your browser — nothing you type is sent anywhere. The quantity and price conversions are the same ones inside LumberIQ itself, built on building materials data structures refined over more than thirty years.
