ROCK FALL game to practice
'Convert grams to kilograms' for 4th grade

Learn how to convert grams (g) to kilograms (kg)

In the metric system, units are related by a factor of 10. This makes it easy to convert between different units of measurement. Grams (g) and kilograms (kg) are both units of mass in the metric system. To convert between them, we need to know that the relationship between the two units is:

1 kilogram (kg) = 1000 grams (g)

This means that there are 1000 grams in a kilogram. To convert grams to kilograms, we need to divide the number of grams by 1000 (to convert kilograms to grams, we would need to multiply the number of kilograms by 1000).

For example, convert 450 grams to kilograms.

450 g ÷ 1000 = 0.45 kg

Example 2, convert 8937 grams to kilograms.

8937 g ÷ 1000 = 8.937 kg


In this topic you are asked to convert masses given in grams to kilograms. The masses range from 1000 grams to 16,140 grams.

Large thumbnail for math game Rock fall

ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.

There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
