Example 2: If the platform slope is 4 per thousand, there will be a difference in
elevation of:
a) 4 mm every 1000 mm horizontally
b) In centimetres: 4 cm every 1000 cm horizontally
c) In metres: 4m every 1000 metres horizontally
Equivalence between the slope and fractions or decimal numbers
Example:
2 percent =
2 = 0.02
100
1.5 percent =
1.5 = 0.015
100
2 per thousand =
2 = 0.002
1000
3.5 per thousand = 3.5 =
1000

0.0035
