Mass: Metric and English 6 🔒

These 10 questions keep grams in focus, first converting ounces into grams and then kilograms into grams.

You could see 8.0 ounces or 2.5 kilograms and answer in grams, mixing a fiddly customary conversion with a clean metric one.

The contrast is the interesting part: turning ounces into grams means dealing with awkward decimals, while turning kilograms into grams is just multiplying by a thousand. Doing both back to back makes it obvious why the metric system feels so much smoother once you are used to it.
