The water you use is measured by the number of gallons you use.
measured as humidity in the air with a hygrometer.
because water is a liquid.
The weight of eggs, water and milk are measured in ounces or cups. The volume of water, eggs, and milk is measured as a liquid. The volume of butter is measured as a solid.
Nowadays they are all measured in gallons and litres
The depth in the ocean is measured by sounding using echo-sounders. Nowadays satellites are also used for this purpose.
Displacement.
it should be kiloliters considering it's water which is measured in liters
The resistivity of water can be measured by using a device called a conductivity meter, which measures the electrical conductivity of the water. The higher the electrical conductivity, the lower the resistivity of the water.
Water potential is typically measured in units of pressure, such as pascals (Pa) or bars, but can also be reported in kilopascals (kPa) or megapascals (MPa).
SI units cover a range of measures. Liquids can be measured in many ways. Your question is not clear, so I will answer all the corners and nooks that I can. water has mass, mass is measured in grams. water has temperature, which would be Kelvin. water can be measured in moles, which would be moles. water can be measured as having a certain amount of kinetic energy or heat, in joules. water volume can be measured in liters, or milliliters. water can have material in it, dissolved or floating, and that can be measured in parts per million, or parts per billion. finally, water can contain acid or base or other substances dissolved, the concentration of these solutes can be measured in molarity, or molar concentration expressed as moles per liter.
No, the purity of water is not measured in cusecs. Cusec (cubic feet per second) is a unit of flow rate, not a measure of water purity. Water purity is typically measured using parameters such as levels of contaminants, minerals, pH, and dissolved solids.
