Weights shift with how packed, ripe or finely chopped an ingredient is, so treat this as a close estimate rather than a lab figure. Frozen fruit in particular settles, so a heaped cup can outweigh a level one.
Why a cup is never just a cup
A cup measures space, not weight, and smoothie ingredients fill that space very differently. Frozen fruit packs into the gaps, greens barely touch the sides, and a spoon of nut butter weighs more than a spoon of seeds. Converting to grams is how a recipe stays the same from one kitchen to the next, and how the numbers on any calculator line up with what actually went in the blender.
Frozen chunks pack tighter than fresh, so a level cup weighs more than you would guess and a heaped one more again. When a recipe matters, weigh it; a kitchen scale removes the guesswork the cup leaves behind.
A cup of loose spinach and a cup of packed spinach are wildly different weights, and both are called a cup. Greens are the one place where a gram figure is far more reliable than a volume, so lean on the weight.
Seeds, nut butters and sweeteners are measured in spoons, and the gram weight of a tablespoon changes a lot between chia, peanut butter and honey. Converting them is how a blend that reads light on paper turns out rich in the glass.
Grams are exact, cups are quick, ounces sit in between. Pick whichever your recipe is written in and convert the odd ingredient out, rather than switching your whole method for one line.
Turn a weight into nutrition
Once you know the weight, the calorie calculator turns your exact amounts into calories, protein, carbs and fat for the whole smoothie.
