But what happens if you only have half a kilogram? How do you write this? How do you convert it to grams?
Remember 1 whole kg is 1000g, so half of 1000g is 500g.
Half a kilogram is sometimes shown like this >>>> 0.5kg.
So…
1.5 kg = 1500 g so that means that… 1500 g = 1.5 kg
2.5 kg = 2500 g so that means that… 2500 g = 2.5 kg
You carry on.
3.5 kg = ____ g so that means that… ____ g = 3.5 kg
4.5 kg = ____ g so that means that… ____ g = 4.5 kg
5.5 kg = ____ g so that means that… ____ g = ___ kg
6.5 kg = ____ g so that means that… ____ g = ___kg
_____ = 7500 g so that means that… 7500 g = ____ kg
_____ = 8500 g so that means that… 8500 g = ____ kg
_____ = 9500 g so that means that… _____ = ______
_____ = 10500 g so that means that… _____ = ______

1000 g = 1 kg so that means that… 1 kg = 1000 g
But what happens when you have less than 1000 g, lets say 800 g. How do you convert this to kg?
Remember that 1000 g = 1 whole kg, so when you have any amounts less than a whole kg you need to use a decimal point.
100 g = 0.1 kg so that means that 0.1 kg = 100 g
200 g = _____ so that means that ____ = 200 g
300 g = _____ so that means that ____ = 300 g
400 g = _____ so that means that ____ = 400 g
500 g = _____ so that means that ____ = 500 g
600 g = _____ so that means that ____ = _____

But what happens when you have more than 1 kg, for example 1100g. How do you convert this?
Partition the number like this> 1000g and 100g. You know that 1000 g is the same as 1 whole kg = 1 kg, and from doing your work on the other sheet you know you write 100 g as 0.1 kg. So, 1 plus 0.1 = 1.1 kg.
1200 g = 1000 g + 200 g = 1 kg + 0.2 kg = 1.2 kg
2700 g = 2000 g + 700 g = 2 kg + 0.7 kg = 2.7 kg
3800 g = ____________________________________________
4400 g = ____________________________________________
5900 g = ____________________________________________
9200 g = ____________________________________________
Look carefully at these next questions. Look how many whole kilograms we have to help you work out the answer. Partition the amounts. For example 1.4 kg = 1 whole kilogram and 0.4 of kilogram. You know that 1 kg = 1000g and that 0.4 kg = 400g. So add them together and your answer will be 1400 g.
2.7 kg = 2 kg + 0.7 kg = 2000 g + 700 g = 2700 g
3.6 kg = _____________________________________________
5.6 kg = _____________________________________________
8.1 kg = _____________________________________________
8.3 kg = _____________________________________________
9.4 kg = _____________________________________________ |
