Why is 1 calorie defined as heat required to raise 1 gram of pure water from 14.5 to 15.5 Celsius?

The amount of energy required to do the same work as one calorie is 4.18JK-1g-1. Writing out all of this in units can get quite confusing to those who aren't good at algebra, and using such a precise value (4.18 is only an approximation) can result in some numbers that have many decimal digits. Like elsewhere in science, people wanted an easier number and symbol to use, so the calorie was invented.

What energy unit is defined as the heat required to raise on kilogram of water by one degree Celsius?
I believe it is Calorie.
What is the amount of heat required to raise the temperature of a substance through ten degree Celsius?
One calorie is needed to heat 1 gram of water 1 degree Celsius
A caalorie is the amount of energy needed to?
Calorie is the unit of heat energy in cgs system. One calorie is the heat energy required to raise the temperature of one gram of water through one degree Celsius. But in MKSA system of units, joule is used as the unit of heat energy. One calorie is equal to 4.180 joule. Calorie is usually used in bio chemical changes.
What is substances specific heat?

What language does the word calorie come from?
calorie (n.)1866, from Fr (French). calorie, from L. (Latin) calor (gen. caloris) "heat," .... In scientific use, largely replaced 1950 by the joule. As a unit of energy, defined as "heat required to raise 1 gram of water 1 degree Celsius" (the small or gram calorie), but also as "heat required to raise 1 kilogram of water 1 degree Celsius" (the large calorie or kilocalorie). See related links for source.
What is the calorie?
amnt. of energy required to raise the temp. of one gram of water by 1 degree celsius
What is the differences between Calorie and kilo calorie?
A calorie is the unit of energy required to raise one gram of water 1 degree Celsius. A kilocalorie, or Calorie, is the equivalent of 1000 calories.
What is a calorie-?
answer:A calorie is a unit of measure used to describe the energy in food. It is defined as the amount of heat required to raise the temperature of 1kg of water 1 degree Celsius at 1 atmosphere pressure, or 4.184 Joules.Another AnswerA calorie is an obsolescent unit of measurement (cgsA system) used to measure energy; it is not simply used to measure the energy available in food, as implied by the original answer. It was defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.The original answer is not describing a calorie, but a kilocalorie which is 1000 calories.
How much energy is required to raise the temperature of 1 g of water 1 degree Celsius?
Energy required to raise 1 gramme of water by 1 degree C = 1 calorie also, 1 calorie = 4.186 Joules
What is the amount of heat needed to increase the temperature of a certain mass of a substance by 1 degree Celsius?
The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
A calorie is the quantity of heat required to raise the temperature of 1 gram of water 1 degree Celsius T or F?
