Metric mass conversion, step by step
Grams and kilograms are the metric weights a child meets on food packets and a kitchen scale.
The question
97.5 kg = ________ g
7.5 kg = ? g
kg → gsmaller unit, bigger number
1 kg =1000 g
7.5 × 1000 =7500
7500 g
- One g is smaller than one kg, and it takes MORE of a small thing to make the same amount. So the number has to get bigger — which means multiplying.
- There are 1000 g in one kg, so that is the number to multiply by.
- 7.5 × 1000 = 7500, so 7.5 kg is 7500 g. Check the direction held: the number got bigger, which is what a smaller unit does.
How it works.
