Question from Tom:

I need a slope of 2 inches every 30 feet what is the percentage to put on my pipe lazer. thank you

Hi Tom,

$30$ feet is $30 \times 12 = 360$ inches so the pipe rises (falls?) 2 inches in 360 inches and hence the slope is

\[\frac{2}{360} = 0.00556\]

which as a percentage is 0.556%.

I hope this is what you need.

Write back if you need more assistance,
