How many kilojoules in steak?

I need more information to answer that! The number of kilojoules in a steak depends on:

* Size of the steak: A larger steak will have more kilojoules than a smaller one.

* Cut of meat: Different cuts of meat have different fat content, which affects the calorie (and kilojoule) count.

* Cooking method: Frying or grilling a steak can add more fat and calories than baking or broiling.

To give you an idea:

* A 100g serving of lean cooked steak (like sirloin) might have around 500-600 kilojoules.

* A 100g serving of fatty cooked steak (like ribeye) might have around 800-900 kilojoules.

To get the exact kilojoule count for your steak, you can:

* Use a nutrition calculator: Many websites and apps let you enter the type and weight of your steak to calculate the nutritional information.

* Look at the nutrition label: If your steak comes pre-packaged, check the nutrition label for the kilojoule content.

Let me know if you have more details about your steak, and I might be able to give you a more precise answer!
