Why is it when you weigh a measured teaspoon of sugar weighs 23 grams but data on wiki and other sites indicate that one only 4 grams?

Difference in measuring methods:

**The weight of a teaspoon of sugar can vary depending on how it is measured. When you use a measuring spoon, you may scoop the sugar, resulting in a heaping or overfilled spoon, adding the total weight. In contraste, when following the standards used in nutritional data and recipes, the sugar is typically leveled off using a knife of other flat object to ensure a consistent measurement.

Variation in grain size:

Sugar comes in different grain sizes, such as caster, granulated, and brown suger. The grain size can affect the density and packing of the sugar, leading to variations in weights for the same volume. Finer grain sugars, like caster sugar, pack more densely than coarse granulated sugar, resulting in more grams of sugar per teaspoon.

Regional differences:

There may be slight regional differences in the definition and standard size of a teaspoon. In some countries, teaspoon measurements are standardized, ensuring consistency across measurements, while in other places there can be variations in the spoon sizes used.

To ensure accuracy and consistency in measurements it's important to follow specific recipe instructions and use measuring tools that are standardized or calibrated according to the recipe or guidances provided by the source of informational.
