# Convert calorie (th) to kilocalorie (th)

## What is a calorie?

Calorie is a metric that was introduced to evaluate heating parameters. It reveals its amount needed to make 1 gram of water warmer by 1°C under standard pressure. Three varieties of this unit are defined and used, namely:

• international cal that was established as equal to 4.1868 J;
• thermochemical or cal (th) that equals 4.1840 J;
• 15-degree calorie that corresponds to 4.1855 J.

As we can see, these options differ by less than 0.07%, so they are interchangeable in measurements that do not require high accuracy.

During the last century, calories were common for energy, work and heat evaluation. Nowadays despite the transition to the standard system, they are still utilized in the heat and power industry, for heating systems and utilities. In addition, other units are derived from them like kilo- and gigacalories that allow describing bigger quantities of heat in a convenient and easy-to-use way.

## What is a kilocalorie?

A kilocalorie is a derivative of calories. To understand its meaning we should first state that a calorie equals the amount of energy that makes one gram of water warmer by 1°C at standard pressure. The term has a Latin origin and the word calor initially meant heat.

Furthermore, the energetic value of food is usually measured in larger units such as kilocalories. One kcal corresponds to 1000 calories. The latter has several estimations in joules. For instance, international cal equals 4.1868 J and thermochemical or th one corresponds to 4.1840 J. Therefore, kcal (th) will have the meaning of 4184.0 J.

It should be noted that dietology and other related areas often omit the prefix kilo- and utilize a calorie with a meaning that corresponds to a kilocalorie. This happens due to historical reasons, since earlier the terms small and large calories were officially used.

## How to Convert calorie to kilocalorie

You might employ a straightforward procedure to convert cal to kcal. 1 kilocalorie is comparable to 1000 calories. Here's how you might accomplish the calorie to kilocalorie transformation:

• Identify the digit of Cl you want to transform into kcal.
• Separate the digit of calories by 1000 to receive the comparable importance in kcal.

Illustration: 2500 Cl: Kcal= 2500 cal / 1000 = 2.5 kcal

So, 2500 calories are analogous to 2.5 kilocalories. This methodology permits you to transform cal to kcal without requiring online instruments or assistance.

To convert calorie (th) to kilocalorie (th), the formula is used,
$\mathrm{kcal}=\mathrm{cal}÷1000$
where the cal (th) to kcal (th) value is substituted to get the answer from Energy Converter.
1 cal (th)
=
0.001 kcal (th)
1 kcal (th)
=
1000 cal (th)
Example: convert 15 cal (th) to kcal (th):
15 cal (th)
=
15
x
0.001 kcal (th)
=
0.015 kcal (th)

## How many calories in a kilocalorie

Cal is a lesser element of power typically employed in scientific contexts. One cal is the warmth power required to increase the 1 gram of moisture heat by 1 dC. In nutritional terms, when we say "calories," we frequently mean kcal.

Kilocalories are a more extensive element of power employed in standard nourishment. In this context, when discussing the power range of foodstuffs, we commonly refer to kcal.

So, to transform from calories to kcal, you breed by 1000, and this modification allows us to comprehend the importance of food in a more practical and relatable way.

calorie (th) (cal (th))kilocalorie (th) (kcal (th))
0.01 cal (th)0.00001 kcal (th)
0.1 cal (th)0.0001 kcal (th)
1 cal (th)0.001 kcal (th)
2 cal (th)0.002 kcal (th)
3 cal (th)0.003 kcal (th)
5 cal (th)0.005 kcal (th)
10 cal (th)0.01 kcal (th)
20 cal (th)0.02 kcal (th)
50 cal (th)0.05 kcal (th)
100 cal (th)0.1 kcal (th)
1000 cal (th)1 kcal (th)
