Digital scales offer precise, easy-to-read measurements (often down to 1 gram or 0.1 ounce), typically include a tare function, and sometimes have advanced features. Mechanical scales are less precise, can be harder to read accurately, don't require batteries, but are generally more robust for heavier items.

The "tare" function (or zero function) allows you to reset the scale to zero after placing a container on it. This enables you to weigh only the ingredients you add, without including the weight of the bowl, plate, or previous ingredients.

Generally, wipe the surface with a damp cloth and mild detergent. Avoid submerging the scale in water unless it is explicitly stated as waterproof. For digital scales, ensure no liquids get into the display or battery compartment.

Yes, you can weigh liquids. The scale will measure the mass of the liquid. For water, 1 gram is approximately 1 milliliter. For other liquids, weighing by mass is generally more accurate than measuring by volume, especially for baking.

Most food scales offer multiple unit options. Grams (g) are generally recommended for baking and precise dietary tracking due to their accuracy. Ounces (oz) and pounds (lb) are common in some recipes. Millilitres (ml) are often used for liquids, but weight is more accurate for dense liquids like honey.
