Measurement system

The initial choice follows your browser region. Your choice is remembered on this device. Gallons are US gallons. Switching units keeps your numbers unchanged and interprets them in the new unit.

Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.

Common mistakes and quick fixes

Usable length · Maximum centre spacing

Mistake: Changing units and assuming the entered numbers were converted.

Fix: Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.

Limits and key assumptions

Mistake: Treating a result as valid outside the described scope.

Fix: Stock arithmetic only, not structural or code approval. Openings, corners, plates, connections and waste must be specified separately; do not treat nominal timber width as centre spacing.

Limits and key assumptions

  • Stock arithmetic only, not structural or code approval. Openings, corners, plates, connections and waste must be specified separately; do not treat nominal timber width as centre spacing.
  • Displayed results may be rounded; rounding does not add measurement precision.
