All of them. Whatever units a country uses are 'customary' in that country.

No. I would use linear units if measuring the swim distance or cubic units if measuring the volume of water. Square units might be useful to see how many people could use the pool before it got crowded but that would depend on whether they were there for swimming or splashing about.
A 60W bulb will use 60W X 1 hour / 1000. this will give you the KWh - the units your electricity company uses to charge you.So 60 X 1 =6060/1000 =0.060 Kwh
You always use square units when measuring area.
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
A 3-ton heat pump typically has a heating capacity of around 36,000 BTUs per hour and a cooling capacity of around 36,000 BTUs per hour as well. These units can vary based on the specific model and efficiency rating.
There are many more than two units in common use for energy. Some of them are: -- newton-meter -- joule -- foot-pound -- calorie -- watt-second -- kilowatt-hour -- horsepower-hour
Kilowatts and horse power are both measures of power and they must be multiplied by time to get units of energy. 1 HP is 746 watts, so a 3-HP pump works at 3 x 746 watts, and probably uses about 3 kilowatts of electrical power input. In one hour that is 3 kilowatt-hours, also known as 3 Units. Obviously in 6 hours it would use 18 kWh etc. etc.
1000galls howmuch per hour
Kilometres per hour or miles per hour for a car. You could use the same units for runners but most would use metres per second or feet per second.
i would use a pump that pushes at least 350 gallons an hour
It would produce 146 units. However, of you are doing this problem for homework, I'd recommend learning how to do it yourself. It's no use to you if someone else does it! :)
The general consensus is that one 'unit' takes an hour to be taken out of your system. So if you compare what you drink, to how many units it has, that should tell you how much time is needed. Use this calculator: http://www.tulleeho.com/ds/dmeter.asp That'll tell you the units. Then in your head just change 'units' to 'hours'. Simples
The number of gallons an open geothermal heat pump uses varies based on its size, and the overall design. The average home system will use 6-10 gallons per a minute and commercial units considerably more.
Any unit of time will do - day, hour, year, etc. If you want to use SI units, use seconds.
25 feet/second, 25 miles/hour; 25 meters/second, 25 meters/hour, 25 kilometers/hour: In science, we would use the metric/SI units.
