Write 3.6 kilograms in grams.

So in order to answer this question, we need to know one of our conversion factors. And that is that one kilogram is equal to 1000 grams. So therefore, if we want to work out what 3.6 kilograms is, well, we’d actually multiply one kilogram by 3.6 to get to 3.6 kilograms.

So therefore, all what we have to do is actually multiply our 1000 grams by 3.6 to actually work out how many grams that would be. And when we do that, that will be 3600 grams. And the way we actually got 3600 grams by multiplying 1000 by 3.6 is gonna be shown over here. So actually, let’s think about the 3.6.

If you got 3.6, that means we’ve got three ones or three units and then a point and then six tenths. And then, if we multiply this by 1000, what this means is that each of the digits is actually gonna move three place values to the left. So our three will go to 1000. And our six from our six tenths will actually go to 100. So what we’re left with is 3600.

Okay, great! Therefore, we’ve actually answered the question. And we can say that 3.6 kilograms is equal to 3600 grams.
