Electrical – air conditioner kwh

electrical

I'm not sure if I am reading my digital electric meter correctly. It appears to say that my house uses 2.1kwh during the day when no one is home, 3.4 during the night and 16kwh during the day when the air conditioner is running.

The first two numbers are believable. Could my air conditioner attach to the house be really using 14kwh during the moment it is running? I tested the meter by turning on 2 lights (40w cfl and a 60w Incandescent). It should be +.1 but it appeared to be +.27 which is 3x what it should be.

My power bill is 550kwh a month which seems average but the numbers i notice seem weird

14kWh = 14,000 watt hours

That means 14,000 watts for one hour, 7000 watts for two hours, or 1000 watts for 14 hours. Given that a central air conditioner might draw 5000 watts, you could easily see 14 kWh in a day.
