Portion size math help

Assuming you are weighing your food, MFP does have calories per gramme, so weigh food, enter using the gramme option

If you use the gram setting for weighing your food, it's pretty easy to enter it without any calculations (or with very simple ones).

Example: if you want to eat 125 g of pizza you simply choose the 1 gram unit from the units drop down menu in your food diary and enter "125" and you're done. Alternatively, you could use the 100 g unit and just put a decimal point 2 numbers in (from the right) in this example it would mean you enter 1.25 if the units are showing 100 g.

If no gram units are available (though you should try to look for those) and it's only in oz, use this link
https://www.google.jo/search?q=50+ounces+to+grams&rlz=1C1GIGM_enJO527JO527&aq=f&oq=50+ounces+to+grams&aqs=chrome.0.57.8899j0&sourceid=chrome&ie=UTF-8#newwindow=1&q=grams+to+ounces&safe=off

Save this to your bookmarks, enter the number of grams in the first box (in your case 125) and the result is shown in the other box (4.40925 oz). You go to MFP and enter 4.4 if the unit is in oz. If the serving shows a weird number like 1.5 oz, again, use the drop down menu to make it 1 oz.

If you are making a custom food entry, just enter the whole amount (1000 calories for a 500 grams of pizza) and make sure to have the serving size at 500 g. This will give you the option later to use the drop down menu and chose 1 g, which will automatically do the calculations for you.

Basically you need to get used to the unit drop down menu when you enter your foods.

how many calories per gram if something is 960 calories for 411 grams

The equation for that is calories/grams (calories divided by grams). 960/411 = 2.336 calories per gram.

Why don't you just add your things as custom food? Make a new item entry, set portion size at 411 g and then you can input any amount you want without having to do calculations (provided you choose 1 g from drop down menu)

If you don't want to do that, in the future just replace the word "for" with "÷", so 960 calories for 411 grams becomes 960 calories ÷ 411 grams. After that, it would be easy to find an answer using a calculator

Thank you for the formula
for things I eat often, I will take your advice and make a custom food.
I often just do the math and enter as "quick calories" because my phone is 7 years old and it takes ages to use MFP database. (also the amounts I want to eat arnt in the dropdown list and so I have to do math anyway to modify the portion size there).
Also my phones internet connect is flakey and I can't access the database from inside half the time.
I will use the make custom food option more ofthen tho thanks for the tip.

I don't have a smart phone, so I enter everything from the website. I spend 5 minutes each day to log the whole day and then adjust as needed. If you have easy access to a computer, that might be a better option for you.

Alright, I will make it even easier for you.

I made a spreadsheet (just enter the values in the yellow boxes) that will help you figure things out faster. You enter total grams and calories in any food you want and it will calculate the calories per gram.

I have also added a couple of useful things that will make it even easier. After you enter the food, you can specify how many grams you are having which will calculate the number of calories per serving. The last option is if you wish to have a certain number of calories of the food, it will tell you how many grams to eat if you only want to have, say, 200 calories.

Note: Please do not change anything other than the yellow boxes.
