Convert the following numbers of calories or kilocalories into joules and kilojoules (Remember: kilo means 1000.)
i>cal
(a)
Interpretation:
Convert 75.2 kcal to joules and kilojoules.
Concept Introduction:
A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.
The given conversion is: conversion of kilocalories to joules and kilojoules.
1 kilocalorie is equal to the 4184 joules and 4.184 kilojoules.
1 kcal = 4184 J and 1 kcal = 4.184 kJ
Thus, conversion factor is given by:
So,
