オンス
オンス is an imperial unit of weight used mainly in English-speaking recipes and labels, while グラム is the standard metric unit (1 オンス ≈ 28.35 グラム).

キログラムN5
グラム is one gram while キログラム is 1000 grams, so learners must watch the prefix carefully when reading or writing weights.
ミリグラム
グラム is a full gram while ミリグラム is only one-thousandth of a gram, so the two are easy to mix up despite the huge difference in scale.
ｋｇ
グラム (gram) is 1000 times smaller than ｋｇ (kilogram), so グラム is used for light objects like food ingredients while ｋｇ measures everyday body or luggage weight.
