Please provide values below to convert attojoule [aJ] to kilocalorie (IT) [kcal (IT)], or change ↔.
attojoule [aJ]
Definition: An attojoule is a unit of energy equal to 0.000000000000001 joules.
Historyandorigin: It is part of the metric system.
CurrentUse: It is used in theoretical physics and atomic-scale measurements.
funfact: The prefix 'atto-' comes from the Danish word 'atten,' meaning 'eighteen.'
kilocalorie (IT) [kcal (IT)]
Definition: A kilocalorie (IT) is a unit of energy equal to 4.1868 kilojoules.
Historyandorigin: It is based on the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius.
CurrentUse: It is used to measure the energy content of food.
funfact: One kilocalorie (IT) is equivalent to 1,000 small calories.

How to Convert attojoule to kilocalorie (IT)
1 attojoule [aJ] = 2.388458966E-22 kilocalorie (IT) [kcal (IT)]
1 kilocalorie (IT) [kcal (IT)] = 4.186799999E+21 attojoule [aJ]
we use cross multiplication method
attojoule [aJ] → kilocalorie (IT) [kcal (IT)]
1 → 2.388458966E-22
1.5 → ?( suppose x)
=>1.5*2.388458966E-22=1*x
by simplifying
x=3.582688449E-22
