Roof Pitch Calculator: Unit Label Check

Write the unit beside both rise and horizontal run before calculation. A number without its unit is not a reusable roof-pitch input.

Rise and run labels with matching units.

Keep the pair readable

Convert measurements to one basis, then record both units with the original rise/run pair. A displayed result cannot restore a missing unit label.

Can I compare unlabeled roof-pitch notes?

Not reliably. Confirm the same unit basis before comparing inputs or results.
