A watt is the product of Amps times Volts. It has nothing to do with a time interval. That said if that wattage is left on for a period of time, say 1 hour then it can be expressed as watt-hours. Because consumption in an average home is larger that just watts it is expressed as (kilo = 1000) kilowatts The meter on your house totals the amount of kilowatts hours you use in a month and this is what you are billed for from your utility company.
1kW is 3,412.13 BTU/hr
Per day means everyday in one time
A typical septic system can handle about 150-250 gallons of water per person per day.
One kilowatt is equal to 1000 watts or 1000 joules per second: 1kW = 1000W = 1000J/s
The multiple of (0.5 kw per hour) X (total hours of functioning) X (the cost of 1kw-hr).
"per diem" means per day. It comes from Latin.
production per screened day- the amount produced in days recorded
Question doesn't make sense. But if you have something that use or generate 5W per square meter, then you get 1kW if you have 200 square meter.
1 kW is equivalent to approximately 3.412 MBH (thousand British thermal units per hour).
1MW = 1000 KW 1KW = 860 Kcal/Hour 1 Kcal = 3.968 BTu.
stream day means 24 hr day.
par jour means by day / per day in French.
