An ordinary bath takes 4-6 units of electric energy and it's usual to have a hot water tank with a 3 kW immersion heater, so it would not be instant for that amount of energy.
But there are instant heaters for showers because they use less energy. A power-shower runs at around 8-11 kW and if the shower takes 15 minutes that would use 2-3 units.
4.5 units
that would be (11*8 )/1000 = 0.088 Units (or KWh)
Power 2: units digit 9. Multiply by 49 again to get power 4: units digit 1. So every 4th power gives units digit 1. So 16th power has units digit 1, so the previous power, the 15th must have units digit 3.
It is not clear what you mean with "units of power".
Watts and horsepower are both units of power.
It depends upon the time ur running ur PC... A 17" monitor consumes in between 70 to 100 W, and ur motherboard will comsume around 150W and each drives i.e. CD,floppy, Hard Drive etc will consume 15W each but remeber they will consume only when they are used, and agian the motherboard has three power supplys 3,5 and 12 V so it consumes only when the power is needed so its very difficult to say ecxactly how mush it will consume within a day ... ok lets say the Monitor , motherboard are working by consuming 70 and 150 W, and other things are used but not so frequently except ur Hard Disk, so the total average power consumption will be around 70+150+15+15(for other component usage) = 250W so if u run ur PC for 10 Hrs a day it will consume 250*10 = 2500Whr = 2.5KWhr = 2.5 Units ... 1 unit is eqaul to 1 KWhr(Kilo Watt hour)... so in a day if ur using ur PC for 10Hrs it will consume 2.5 units only. i.e. in a month 75 units.
squared as in square units and to the third power it would be cubed as in cubed units

Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
This would be 30 watthours, or 0.030 kilowatthours
