measuring electric usage

[iluvtorts]

Several people have mentioned an electrical device to measure usage, on for instance a heater. Im not sure if this is the right place to put this question. If someone could please tell what it is called and where to get one. Thank You for the help.

The simple/easy to use plug in kind is called a kill-a watt

Here is a formula for cost.........
The running cost of an electrical appliance is determined by:
•its capacity, expressed in Watts (W) or kilowatts (kW) (1000 W = 1 kW)
•your electricity tariff - typically around 26 cents per kWh for normal residential electricity supply.
•how long you use them for

To work out the running cost:
1.take the capacity, in kilowatts (if it is in Watts, divide by 1000 to get kilowatts)
2.multiply by your electricity tariff if you know it, if not use 26. The answer is how much it costs to use the appliance, in cents, for an hour
3.if you are going to be using the appliance for a period of time, multiply by the number of hours to get the total. Don't forget that the answer is in cents

As an example, if you use a 2.4 kW heater for 4 hours a day and pay 26 cents per unit for electricity then:

2.4kW heater x your electricity rate 26 cents = 62.4 cents an hour to run

62.4 x 4 (number of hours you use it a day)

= $2.50 to run each day

Or, the device you might be talking about, is a device that measures the UVB being put out from a UVB bulb, such as the Mercury Vapor Bulb.
