Why your kitchen scale is your most honest tool
Your measuring spoons and cups quietly lie. The same tablespoon can hold almost double the food when it is heaped, so a cheap digital scale is the one tool that always tells you the real number.
Your eyes lie to you at the dinner table. Your spoons lie too. One tablespoon sounds like a fixed amount, but it is not. Heap it, and it holds almost double the food. This short read is about the one tool that never lies: a cheap digital kitchen scale.
A tablespoon is always the same amount of food.

A 'tablespoon' sounds like a fixed number. It is not. Level a teaspoon of sugar and it weighs about 4.2 grams. Heap it the way most of us do. It jumps to about 7.5 grams. That is nearly double the sugar from the very same spoon. Oil is the same story. One level tablespoon of oil is about 120 kcal. A spoon you do not level quietly adds more. The spoon only tells the truth when you flatten it. Most days, you do not.
Cups and spoons are guessers; the scale is honest
Measuring cups and spoons change from one kitchen to the next. One maker's cup is bigger than another's. Few of us level a spoon the right way. A university food team says it plainly. Cups and spoons vary by maker and by style. An item weighed on a scale is usually more accurate. In one study, people used a measuring cup to guess portions. The median error was about 88 percent. People mostly guessed too much. The cup was the worst tool of all. A digital scale has no such moods. Put the food on. Read the grams. Done.
The rounded-spoon trap, by the numbers
Use the scale so it actually helps you
The bottom line
Your spoons are storytellers; the scale is a witness. One level teaspoon of sugar is about 4.2 g. A heaped one is about 7.5 g — nearly double, from the same spoon. One level tablespoon of oil is about 120 kcal, but only if you level it. A cheap digital scale skips the whole guess. Burnie is FREE, so an honest log costs you nothing but a few seconds. Weigh the few dense foods that hide calories, and your numbers will finally match your effort.
