# Math Problem: Finding the carbs in 40% milk fat whipping cream

(Ketopia Court Jester) #1

Alright, mathy types, wake up!

If a 88% milk fat whipping cream has 6.64 grams of carbs per cup, then how much would a 96% milk fat whipping cream have? Those are the numbers I found after an hour online. (I have no life.)

I came up with 0.38 grams per tablespoon. Did I win?

Not sure what youāre asking, the title of the post says 40% milk fat whipping cream, but then you ask about 96% milk fat whipping cream. Well I donāt really know anything about whipping cream, but the math isnāt a problem. If the relationship between carb content and milk fat content in whipping cream is a linear relationship, then this can be solved using simple proportions. So, given your figures, a cup of whipping cream with 96% milk fat would have 7.24 g of carbs. There are 16 tbsp in a cup so there would be 0.45 g of carbs in 1 tbsp of 96% milk fat whipping cream.

Now if the relationship between milk fat and carbs in whipping cream is not linear, then one would have to have a math function that would express the relationship mathematically. Iām an engineer, not a nutritionist or dietitian (or whatever profession understands these kinds of things about food) so I have absolutely no idea if my assumption about linearity is true or not and so have no idea if my calculations above are correct or not.

Our whipping cream is 35% fat. And ā¦ read the label

Yeah those numbers didnāt make sense to me, but I used them anyway. I searched for the nutritional info on whipping cream and what I found was 44.4 g of fat in 1 cup (120 g) of whipping cream, so thatās 37% fat.

Iām fairly new here so perhaps ābaconā¦ā really is a jester and is rolling on the floor in glee that someone actually tried to solve this problem.

Agreed. Except a cup is 250g unless the cream has a very low sg

(Steve) #6

Sorry, 1 cup whipped is 120 g. I didnāt notice the whipped in the nutrition info.

#7

Oh. That sounds right

Listen up, buttercup. The label on my whipping cream says less than 1 carb per tablespoon. That could be 0.3 grams per tablespoon or 0.9 grams, no clue. I had to spend almost an hour tracking down fat percentages and comparable brands and doing MATH that required even more coffee and HWC to get here. If youāre not part of the solutionā¦

(sigh) Iām going with my conclusion that itās a reverse ratio and my findings are close enough.

The only thing rolling at this point are my eyes.

Butter is typically 80% milk fat give or take a little. I donāt think 88% or 96% fat cream is a possibility.

(What The Fast?!) #12

If it helps, to be labeled <1 carb, it has be 0.4 or less. If it registers higher, they have to list 0.5 or round up to 1. I have seen several HWCās that say 0.4g, so my guess is regular (US) HWC is about 0.4g per cup.

(Ketopia Court Jester) #13

Yaaay! Thatās incredibly helpful, thank you. And it verifies my findings. Iām goinā with 0.38 g and having another cup. (slurp!)

Very close, but not exactly. There is no ā.5ā that can be listed, as far as I know (and as far as Iāve seen).

My understanding is that itās:

ACTUAL/LISTED

.0g - 0g
.1g - 0g
.2 - 0g
.3 - 0g
.4 - 0g
.5 - āContains less than 1 gā or āless than 1gā
.6 - āContains less than 1 gā or āless than 1gā
.7 - āContains less than 1 gā or āless than 1gā
.8 - āContains less than 1 gā or āless than 1gā
.9 - āContains less than 1 gā or "less than 1g"
1.0 - 1g
Etc.

So tell me how many carbs are in a tablespoon of 40% milk fat whipping cream.

#16

This page says <1 . But they also say there are 16 tablespoons in a cup. Thatās a skimpy 15g tablespoon. I can get a lot more cream onto one tablespoon

#18

Who the heck can have a tablespoon of cream??? Iām assuming the cream is 35-36% fat.

Cream is to be measured in cups - perhaps a half cup or so in your tea if you drink less than 1L at a time.

There is about 6.6g of carbs in a cup of cream. That is about 0.415g per tablespoon.

Thats the same as cream here in the UKā¦ I have a tablespoon in my triple shot americano and that gives 0.39 g of carbs per mug.

Brad, you are a god. Unfortunately, my cream isnāt listed:

Darigold, 40% Heavy Whipping Cream, UPC: 26400 23220

The label claims 6 grams of fat per 15 ml with āless than 1 g carbā per 60 calorie serving.

āXactly. My morning coffee is so keto-nuclear at this point that Iām ruined for all drive-thru options. This saves money but Iām rockinā a heavy thermos on long drives that refuses to keep it lip-burninā hot like I like it. The sacrifices I make.
