(with conversion factors)
Yes, it's just that the point of a kwh is that it has mixed time units, so I'm not sure if in this context it is useful to simplify or convert to base units (via f=ma). But sure, if that's what you are looking for...nineteen said:Awesome. Thank you very much. I also figured something like this, as kWh is a unit of energy, it will ultimately equal the dimensions of energy, so the dimensions will be ML2T-2
A kWh (kilowatt-hour) is a unit of energy commonly used to measure electricity consumption. It is equal to the amount of energy used by a 1,000 watt appliance in one hour.
To calculate kWh, you multiply the power consumption in kilowatts (kW) by the time in hours (h). For example, if an appliance uses 2 kW of power for 3 hours, the calculation would be 2 kW x 3 h = 6 kWh.
A kWh is a unit of energy, not a physical object with dimensions. However, it can be converted into other units of energy, such as joules or BTUs, which do have physical dimensions.
A kWh is a unit of energy, while a kW (kilowatt) is a unit of power. Power is the rate at which energy is used, while energy is the total amount of work or heat produced. Think of it like a car - power is how fast it can go, while energy is how far it can travel.
Electricity is typically measured in kWh because it is a more practical unit for measuring the amount of energy used in a given period of time. It allows for more accurate billing and monitoring of electricity usage compared to other units, such as joules or BTUs.
