BTU's or calories are directly related to the heat capacity of a substance or the heat produced in a reaction. All energy can be expressed in Joules, and for heat the relation is 4.2 Joules per calorie, this is called the mechanical equivalent of heat.
Thermal energy is measured in joules (j).
1 calorie = 4.2 Joules
Answer
In SI, all forms of energy are expressed in joules(J).
The British Thermal Unit (BTU) is an imperial unit for energy, rarely used anywhere outside the United States. The calorie is an obsolete (cgsA) unit despite being used (kilocalories) to some extent in the food industry.
The terms, 'heat energy' and 'heat capacity' are both obsolete, having been replaced with 'internal energy' and 'specific heat capacity' (which is expressed in joules per kilogram kelvin).
Work and heat are both described as energy in transit, and measured in joules.

What unit is used to express amount of thermal energy?
The unit used to express the amount of thermal energy is the joule, which is also the standard unit of energy in the International System of Units (SI).
The SI unit of electrical mechanical and thermal energy?
The SI unit of electrical energy is the joule (J), the SI unit of mechanical energy is also the joule (J), and the SI unit of thermal energy is the joule (J).
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 English measurement of thermal energy?
Traditionally the BTU (British Thermal Unit), but now we usually use kilojoules
What is the unit used to measure thermal energy besides joules?
The unit used to measure thermal energy besides joules is the calorie. It is commonly used to quantify the energy content in food and beverages.

A British thermal unit is a unit of energy that is equal to about 1055 joules. A British thermal unit is the amount of energy that is needed to heat or cool one pound of water by one degree Fahrenheit.

The international unit for energy (and work) is the joule.
What kind of energy do calories produce?
Calories don't "produce" energy; calories are a UNIT OF ENERGY.
