The Heavy vs. The Light

The easiest way to remember which is which is to look at your hands:

• Grams (g) are for the small stuff. Imagine holding a single paperclip or a grape. It’s so light you might even forget it’s there!

• Kilograms (kg) are for the big stuff. Imagine holding a big, heavy dictionary or a liter bottle of soda. You definitely feel the muscles in your arm working!
