Hi Aditya,

As 14.2 gram of butter contains 101.8 kcal (426 kJ) of energy.

Then 1 gram of butter will contain 7.16 kcal (30 kJ) of energy.

Then, 1 mg (milli gram) of butter will be containing 71.6 cal (300 J) of energy.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!

So , I can help you with this information if you can tell the butter brand. For example , Amul Tablebutter contain 722 kcal energy , and 720 kcal energy from fat.
