Gradient [1]

A slope. It might be an incline (going uphill) or a decline (going downhill). A gradient is typically expressed either as a ratio, for example 1 in 100, or as a percentage, for example a 1% gradient. Each of these examples mean that there is a 1-unit difference over 100 units; so over 100m this will mean a difference in height of 1m. Also called a Fall or Slope.
