Food labels often indicate energy in joules and calories. A jar of jam contains 1030 kJ (245 kcal). Check if that is correct.

It is not correct.

The correct conversion is:

1030 KJ = 246.18 KCal.

Explanation:

To know if 1030 KJ is equivalent to 245 KCal, we shall convert 1030 kJ to kcal. This can be obtained as follow:

4.184 KJ = 1 KCal

Therefore,

1030 KJ = 1030 KJ × 1 KCal / 4.184 KJ

1030 KJ = 246.18 KCal.

Thus, 1030 KJ is equivalent to 246.18 KCal.

From the above calculation, we can see that:

1030 KJ ≠ 245 KCal

Rather,

1030 KJ = 246.18 KCal.
