The joule is the unit of energy in the International System of Units, also known as SI. It measures heat, electricity and mechanical work. It was named after English physicist James Prescott Joule. See the related links for more information.
The joule is a derived unit equivalent to a newton-meter, or a kilogram-meter squared per second per second.
A joule is also:
- A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for a period of time of one second.
- A unit of energy equal to the work done when a force of one newton* acts through a distance of one meter.
[* In the meter-kilogram-second (MKS) system, a newton is the unit of force required to accelerate a mass of one kilogram one meter per second per second, equal to 100,000 dynes. The unit is named after Sir Isaac newton.]
What else can I help you with?
Energy and work are measured in the SI unit called the?
Energy and work are measured in joules.
Power is measured with what unit of energy?
Power and energy are different physical quantities. They have their own units in SI system Unit of energy is joule and that of power is watt. Of course electrical energy is measured as kW h
What unit measured energy?
The international unit for energy is the joule.
Is joule used on temperature scales?
No. A joule is a unit of energy within the SI system.
When work is measured in joules and time is measured in seconds power is measured in what unit?
Power is measured in watts when work is measured in joules and time is measured in seconds.
Energy and work are measured in the SI unit called the?
Energy and work are measured in joules.
What is the unit of measurement used to express the energy emitted per second?
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power.

Is mass measured in joules?
No, a Joule is a unit of energy. Mass is measured in kilograms (or grams)
What unit measured energy?
The international unit for energy is the joule.
In what unit is energy measured?
The SI unit for energy is the joule.
What are energy measured in what?
The SI unit for work and energy is the joule.
What are quantities for a joule?
A joule is a unit of energy in the International System of Units (SI). It is equivalent to the work done by a force of one newton acting over a distance of one meter. Other quantities that can be expressed in joules include heat, electrical energy, and mechanical work.
Is joule used on temperature scales?
No. A joule is a unit of energy within the SI system.
Ratio that compares 2 quantities measured in different units?
ratio that compares 2 quantities measured in diiferent units
Can heat be measured in Kelvin or centigrade degrees?
No. Those are units of temperature. Heat is measured in units of energy, such as the joule.
Milk is measured in what quantities?
Milk is a liquid. liquids are measured in liters.
