Grade (slope)

For other uses see: Gradient (disambiguation)


The grade (or gradient) of a road or railway line is a measure of its steepness. It may be expressed as a percentage or in other ways.  For example, a gradient of 1% may also be expressed as 1 in 100.  This means that the road rises or falls by 1 metre for every 100 metres of forward travel.
