teach after on problems time. So for a says, the density of water is one graham person in years. Cute. Then we want to convert this to kilograms per meter so it's times by one converting factor that so takes grams away. So for one kilogram there's 1,000 grams so that all changed the creams. Two kilograms and now we need to change these centimeter cubes meters cute. So one spotter practice by the second conversion factor Centimeter Cubism bottom here so need centimeters appear in meters here. So for one meter there's 100 centimetres and since it's kilometres cute, we have to queue this conversion factor. So if we multiply this all out, you see that he's set a meeting is cancelled Visa and we're left with 1,000 kilograms per meter. Cute as the density of water. Okay, cool. Moving on to be says the density of blood is 1,050 kilograms per meter cubed, we want to convert this back two grams per centimeter. Compare how this is to that. So we're going to do just the opposite. Let's get rid of this kilograms and convert that to grains now. So we know for one kill grand. There's 1,000 great homes now for one need, er there's 100 student leaders. And since it's me who's cute, they keep this and we multiply us out When we see this is one point 05 grains personally, if you perfect now on to see this is how many cubic centimetres. But then how many kilograms are there in a wonder vial of drinking water? And how many pounds? So one leader, It is 1,000 mill years water So and we also know that conversion that this is 1,000 soon? Yes, Cube, because a cubic centimeter is a mill leader. So now if we have this in cubic centimeters going to multiply this by density, take the weight so we won't find us by one Krayem for cubic centimeters and we see that this is exactly 1,000 crams or one kilogram ofwater. Now, if we just you know, the pounds, we just need to cover this one killing, murdering two pounds. Who we know that community anything governors. One kilogram is 2.2 pats perfect
