What is a gram?
A gram (g) is a base unit of mass that’s used in the metric system. One gram is equal to 1,000 milligrams (mg), and it takes 1,000 grams to equal 1 kilogram (kg).
The metric system is used by most countries, which is why it’s the most common unit of measurement used by chefs and home cooks for measuring dry ingredients. It’s more consistent than measuring by cups or tablespoons because there’s no risk of lumps or air pockets.
What is an ounce?
An ounce (oz) is a unit of measurement for weight that’s typically used in America, Liberia, and Myanmar (countries that follow the US customary system or British Imperial system). It takes 16 ounces to equal 1 pound (lb).
Tips for measuring dry weight
I always recommend having a digital kitchen scale when cooking or baking. It’s the only way to guarantee accurate measurements when following a recipe. They even allow you to bounce back and forth between units and get accurate measurements for wet and dry ingredients like flour, brown sugar, or honey.
Here are the steps needed to get precise measurements with a digital scale:
- Place a bowl on the scale
- Turn the scale on (if the scale is already on, press the ‘tare’ button to zero out the weight of the container)
- Select your desired unit
- Add the ingredients to the bowl until you reach the desired weight
