In the Internation System of Units there are only seven base units of measurement and the joule is not one of them. It isn't needed as a unit because it can be derived from the base units. The joule is really just a 'convenience' because it's much easier to say or write than its definition which is kg.m2.sec-2. For more about this you might be interested in reading the wikipedia page about the Internation System of Units.

What are the units for energy and power?
The SI units are as follows: The unit for energy is the Joule. The unit for power is the Watt, which is equal to Joules/second. (Therefore, you might also say that a Joule is a Watt times a second.)
What unit is represented for coulomb per second?
The ampere is one of seven SI base units, and is defined in terms of the force it produces between two, parallel, current-carrying conductors. It is incorrect to say that an ampere is 'defined' as a coulomb per second, although it is certainly 'equivalent' to a coulomb per second.The coulomb is a SI derived unit, and is defined in terms of the ampere and the second. In fact, it is a special name given to an ampere second.
A object has one joule of potential energy explain what does it means?
We know that energy is defined as the ability to do work.So an object has one joule of potential energy means that the body has capability to do a work of one joule. We may say that the object with 1 joule of potential energy is the force field and our work is stored in displacing the object against the field
Can you convert from joules to photons?
Joules is a unit of energy; watts is a unit of power. You can't just convert it. The relationship between the two is: power = energy / time in units: watts = joules / second
How do you say Pence in German?
Pence, as a unit of currency of the British Pound is the same in German. It is derived from the Old English Pennig and has the same etymological root as the now defunct German Pfennig.
Is liter the base unit for volume in the metric system?
A derived unit is obtained from a combination of fundamental units. For example, a fundamental unit is a centimeter(cm). A derived unit is a cubic centimeter(cm3), or a cube that is a centimeter on each side. Derived units are used for measuring liquids. A liter is also a derived unit. s-1 is a derived unit too, even though it only consists of one fundamental unit.There is no such thing as an SI 'fundamental' unit. The term you are looking for is a 'base' unit. Taking this further, the SI base unit for length is the metre, not the centimetre. Derived units are combinations of base units -for example, a metre per second is a derived unit (for velocity), made up of the base units metre and second.
Why are energy and work measured in same units?
Work and Energy have the same unit because they are intimately related by the Work-Energy Theorem. This states that the Work done on an object moving from point A to point B is the difference in the Kinetic Energy it has at the two points. In simplified form it says that in order to do Work, you must use Energy; you can never do Work without using Energy, and so for convenience we give them the same unit. You didn't ask about Heat, but it really ought to be mentioned here, too; when you use Energy to do Work, some of the Energy usually gets converted to Heat by friction, so we can and do also use the same unit for Heat. Work and Energy and Heat are not the same thing, but they are inextricably related. By extension, the Theorem lets us define forms of Energy other than Kinetic Energy which enable us to do Work: Chemical Energy, Electrical Energy, Nuclear Energy, Gravitational Energy, etc. The SI unit of work or energy is Newton-meter (Nm). Another name for it is Joule (J). 1 joule is defined as the work done when a force of one newton acts over one metre of distance. 1 joule is also the amount of heat dissipated when a current of 1 ampere passes through a resistor of 1 ohm for 1 second (or 1 watt-second).

How do you say how are you in Philippines?
In the Philippines, you can say "Kamusta ka?" to ask someone how they are.
How much work does atlas do while holding the earth on his shoulders?
It is only an imagination. No person such as Atlas who is holding the earth on his shoulder. Any way if we accept the same then as he lifts the earth against the gravitational attractive force say F through a distance which equals to his height of his shoulder right from his foot, say H, then work done will be F*H joule.
What does power mean in scientific terms?
Power is defined as energy per unit time. You can also say 'rate of doing work'.
Which term defined as the measure of the mass per unit volume of substance?
mass per unit of volume is infact NOT density, it is DERIVED!!
How you convert 36watts in joules?
Watts is a unit of power; Joules is a unit of energy. Watts means Joules/second, so you would need to know how long a machine that uses 36 watts (for example, certain light-bulbs) is used.36 watts is simply 36 Joules per second; this is the same as 2160 Joules per minute, or 129,600 Joules per hour.Since the electricity bill is measured in kWh instead of Joule (1 kWh = 3,600,000 Ws = 3,600,000 Joule), you might also say that a device that uses 36 watts uses 0.036 kWh every hour.
