Why do scientist use the joule as the unit of measurement of energy instead of calorie?

Because it is defined by fundamental SI units, ie the meter and the Newton, which is a force. 1 Joule is the energy used to move 1meter against a force of 1 Newton.

What describes an association between energy measurement and foods?
A calorie
How is a calorie and thermal energy related?
One calorie is the thermal energy required to raise one gram of water by one deg C. (Note that in food, the calorie used is actually the kilocalorie. Also that one calorie = 4.2 Joules.)Another AnswerThe calorie is an older unit of measurement for energy and work. It was part of the centimetre-gram-second-ampere (cgsA) system, which has long been replaced by the SI system. The modern, SI, unit of measurement for energy and work is the joule.
Why do you suppose scentists use the joule as the unit of measurement of energy insteasd of the calorie?
The definition of the joule is based on more general principles. The calorie is defined by properties specific to water.
What is the English measurement of thermal energy?
Traditionally the BTU (British Thermal Unit), but now we usually use kilojoules
What is the unit of measurement in energy?
1) The unit for any type of energy is the joule. 2) In some contexts, such as food, the old-fashioned unit "calorie" is still used.
Is a calorie a mineral?
No, calorie is not a mineral ,it is energy.............
What describes an association between energy measurement and foods?
A calorie
What is the use of heat as a convenient measurement of chemical energy in any reaction?
Energy is measured in joules. Sometimes the older unit "calorie" is used instead - this is a unit defined on the basis of heat, but it is still a unit of energy.
Are calories the same size as molecules?
A calorie is a measurement of energy and has no size.
How much energy does it take to lose a lb?
3500 Calories.....A Calorie is simply a measurement of energy expenditure
A calorie is a unit of measurement used to measure what?
Wrong. The calorie is not an SI unit, and it is confusing because it comes in two varieties: gram when spelled calorie (small c) and Kilogram when spelled Calorie (Capital C). The SI energy unit is the Joule.

Is calorie compound or element?
It is neither. !!! Calorie is an old-fashioned Imperial measure of Energy. In modern science we use 'Joules'.
What is heat energy measurement?
The energy unit is the Joule, J in the International System of units;Calorie is also an energy unit;British Thermal units, BMU.1 BTU = 1055 J1 calorie = 4.18 J
What is the unit of measurement of energy needed to heat one kilogram of water by 2 degrees F?
It is a calorie
Is a calorie part of the metric system?
calorie was but is now obsolete. Joule and kJ are used instead because they are the SI energy unit
