Joules are usually used by scientists. Energy is energy, so energy (and work) in physics are always measured in joules. However, if you are talking chemistry, often calories are used. The "calories" in food are actually kilocalories. That is, 150 calories worth of chips are in reality 150 kilocalories, which equals 150,000 calories. (kilo means "times 1000")
Here is a clip from wikipedia on calories:
A calorie is a unit of measurement for energy. In most fields, it has been replaced by the joule, the SI unit of energy. However, the kilocalorie or calorie remains in common use for the amount of food energy. The calorie was first defined by Professor Nicolas Clément in 1824 as a kilogram-calorie and this definition entered French and English dictionaries between 1842 and 1867. The calorie was never an SI unit. Modern definitions for calorie fall into two classes: * The small calorie or gram calorieapproximates the energy needed to increase the temperature of 1 gram of water by 1 °C. This is about 4.184 joules. * The large calorie or kilogram calorie approximates the energy needed to increase the temperature of 1 kg of water by 1 °C. This is about 4.184 kJ, and exactly 1000 small calories.
it is something that i do not no lol

What unit of measure is used to measure earth's heat?
The unit of measure used to quantify the Earth's heat is the joule (J), which represents energy. Energy inputs and outputs related to the Earth's heat are often measured in joules to understand energy balance and temperature changes.
How do you measure heat energy?
Heat energy can be measured using a unit called a calorie or in more common units such as joules or kilojoules. Devices like thermometers or calorimeters can be used to measure temperature changes, which can then be used to calculate the amount of heat energy transferred.
What is kila joule?
A Joule is a unit of measure for energy. The unit breaks down into N*m (Newton meters). A kJ is 1x10^3J.
How is heat measured Identify instruments used to measure heat?
Heat is measured in units of energy, such as joules or calories. Instruments used to measure heat include thermometers, calorimeters, pyrometers, and infrared cameras. These instruments rely on principles of thermal expansion, specific heat capacity, and electromagnetic radiation to quantify heat energy.
What does BTU means in science?
It is a measurement of heat energy or the output of a heating or cooling device. A British Thermal Unit is the amount of energy needed to raise or lower the temperature of one pound of water by one degree F.
What unit is used too measure energy?
Energy of heat = Joules (J)
Name 3 different units of heat energy?
Calorie: a unit of heat energy commonly used in nutrition to measure the energy content in food. BTU (British Thermal Unit): a unit of heat energy often used in the United States to measure energy required for heating and cooling. Joule: a unit of heat energy in the International System of Units, used to measure heat and mechanical work.
What unit of measure is used to measure earth's heat?
The unit of measure used to quantify the Earth's heat is the joule (J), which represents energy. Energy inputs and outputs related to the Earth's heat are often measured in joules to understand energy balance and temperature changes.
What does a kcal weigh?
A kilocalorie is not a measure of weight. It is a measure of energy
Joules could be used to measure what?
work and energy +++ The Joule (J) is the unit of energy, alone, not of work. The Watt (W) is the unit of power, i.e. work done in converting or transferring energy, and 1W = 1J/s.
What is a unit of heat used to measure the energy your body uses and the energy your body uses the energy it receives from food?
A calorie is a unit of heat used to measure the energy your body uses and the energy it receives from food. It represents the amount of energy required to raise the temperature of one gram of water by one degree Celsius.
What is the unit of measurement used to measure the amount of heat produced during metabolism?
The unit of measurement used to measure the amount of heat produced during metabolism is kilocalorie (kcal). This unit is commonly used to quantify the energy content of food as well.
What symbol is used to measure energy?
If you refer to the unit, the international unit for energy is the joule; the symbol is "J".
What are the units used to measure internal energy and heat?
Heat is also a type of energy, so energy units would be used in both cases. The standard (i.e., international) unit for all sorts of energy is the joule.
What is the unit to to measure thermal energy?
The customary unit is called the Btu, or British thermal unit. The metric unit is the joule. The joule is the standard metric unit for measuring any type of energy, including heat.
What is the name for the unit used to measure the energy of an electromagnetic wave?
The unit used to measure the energy of an electromagnetic wave is called a photon.
What is a unit of measure for all forms of energy?
The international unit for energy (and work) is the joule.
