1 cusec is equal to 28.317 litres. A cubic foot per second is the volumetric unit of flow called the cusec value. The equivalent in litres per second is 28.32. Cusec is shown in litres. Cubic feet per second is denoted by cusec.

1 feet = 30.48 cm

So,

1 cubic feet = 30.48 cm x 30.48 cm x 30.48 cm

= 28,316.85 cm3

= 28,316.85/1000 [As 1000 cm3 = 1 litre]

= 28.317 litres

### Measurement of Litres

Litres are frequently used for substances that are measured using the volume or container size (such as liquids and solids that can be poured), while cubic metres are most frequently used for substances that are measured using either their displacements or their dimensions. In some calculated measurements, like density (kg/L), the litre is frequently also employed, making it simple to compare the measurement to the water density.

When measured at maximum density, which happens at roughly 4 °C, 1 litre of water has a mass that is almost exactly equal to one kilogramme. Therefore, one millilitre (1 mL), or 1000th of a litre, of water has a mass of approximately 1 g, and 1000 litres of water have a mass of approximately 1000 kg (1 tonne or megagram). This is true because the gram's original definition, which stated that it was equal to the mass of one millilitre of water, was dropped in 1799 due to the fact that water's density varies with temperature and, very slightly, with pressure.

Therefore, 1 cusec = 28.317 litres.

Summary:

## 1 cusec is equal to how many litres?

28.317 litres are equivalent to 1 cusec. Cusec is the cubic foot per second which is the volumetric unit. Cusec is shown in litres which is a measure of volume based on the size of the container.
