The total quantity of water in one hectare-centimetre is:

Concept

A hectare-centimetre is a unit of volume: it is the volume covering an area of one hectare to a uniform depth of one centimetre. Volume is area multiplied by depth, and cubic metres are converted to litres using 1 m3 = 1,000 litres.

Application

1. Area = 1 hectare = 10,000 m2.

2. Depth = 1 centimetre = 0.01 m.

3. Volume = area × depth = 10,000 × 0.01 = 100 m3.

4. Water quantity = 100 × 1,000 = 100,000 litres.

Cross-check

In centimetres, one hectare is 100,000,000 cm2. Multiplying by a depth of 1 cm gives 100,000,000 cm3; dividing by 1,000 cm3 per litre again gives 100,000 litres.

Therefore, one hectare-centimetre contains 100,000 litres of water.
