Question

How do we just know it’s grams or kilograms? because my son doesn’t know what to say as do I. Frankly it’s confusing please help.

Answer 1

The kilogram is also divided into 1000 parts called grams. It is easy to remember as kilo at the start of a word means thousand, so 1 kilogram = 1000 grams. The symbol for grams is g, so 1000 g = 1 kg. megatonne is not actually used, although theoretically it could be used as a unit of mass.

Answer 2

Answer and Step-by-step explanation:

If you see a number or fraction or anything we g beside it, such as:

4.2g

6g

$\frac{7}{6} g$

^ That is grams

If you see anything with kg next to a number, fraction, e.t.c, such as

$\frac{1}{2} kg$

5kg

6.2kg

^ That is kilograms
