One ha cm of water is equal to

• Let's break down the units and calculations:
-1 hectare (ha) = 10,000 square meters (m²)
-1 centimeter (cm) of water = 0.01 meters (m) of water depth

• So, 1 ha cm of water represents a volume of:
-10,000 m² (area) × 0.01 m (depth) = 100 cubic meters (m³) of water

• Now, let's convert this volume to tonnes and liters:
-1 m³ of water = 1000 liters
-1 m³ of water = 1 tonne (metric ton)

• Therefore, 100 m³ of water is equal to:
-100 m³ × 1000 liters/m³ = 100,000 liters
-100 m³ × 1 tonne/m³ = 100 tonnes
-Hence, 1 ha cm of water is equivalent to both 100 tonnes and 100,000 liters of water.
🔑Key Points
Irrigation water can be measured in terms of unit of volume, units of flow and depth.
-1 hectare cm of water means the amount of water required to spread over 1 hectare to a depth of 1 cm.
-1 cusec= 28.3 litres
-1 cumec= 1000 litres
-1 ha mm= 10000 litres
-1 ha cm= 100000 litres
-1 ha m= 10000000 litres
