The number of kilowatts used by a device in one hour. This gives you the rate at which energy is consumed.
To measure a physical quantity correctly and need to compare it with some standard quantities. Thus a standard unit is needed to measure a quantity correctly.
You have not specified the quantity of water. You cannot measure one fifth of an unspecified quantity.

Electricity is measured in kilowatt-hours (kWh) rather than volts, which is a measure of electrical potential. The total electricity consumption in a country can vary widely; for instance, the United States consumed about 4 trillion kWh in 2021. To convert this energy usage into volts, you would need to know the total power and the system's voltage, as volts alone do not represent the quantity of electricity used over time.
The measure of quantity energy is energy, typically measured in joules (J) or kilowatt hours (kWh). Energy is the ability to do work or produce heat and can exist in various forms such as kinetic, potential, thermal, or chemical energy. It is a fundamental concept in physics and plays a crucial role in many aspects of our daily lives.
A unit is numerically-equal to a kilowatt hour and is used to measure energy consumption.
You cannot. kWh is a measure of energy. There are lots of people in the world who use energy but have no use for a dollar. Kwh and dollars measure different things and, according to the basic principles of dimensional analysis, conversion from one to the other is not valid.
To convert metric tons to kilowatt-hours (kWh), you would first need to know the energy content of the material you are working with. Once you have this information, you can then use the conversion factor to calculate the equivalent in kWh. The formula to convert metric tons to kWh is: (metric tons * conversion factor) = kWh.
1 BTU = 1.055 kilojoules. I'm not sure what you mean by 'BTUday'. BTU is a quantity of energy, so BTU x Day has no meaning. BTU/day is a rate of energy, ie power. KW is a rate, and KWh a quantity. So what are we comparing? 1 BTU/sec = 1.055 kJ/sec = 1.055 KW. So 1.055 KWsecs = 1 BTU, 1 KWh = 3412 BTU. It also follows that 3412 BTU/hour = 1 KW. Hope this has helped. Just remember to compare quantity with quantity, and rate with rate, and don't mix them up.
What can measure only one quantity of liquid?
Assuming it is used to produce electricity, it will be sold in kWh, or MWh probably on a commercial scale.

Mass
No. ppm is a pure number - a ratio. g per kwh is a measure of mass per energy with dimensions: [L-2][T2]
