How can i find out the following and calculate them?

Question

The values of:
a) 2.750m in mm
b)1.600km in m
c)6.500g in mg
d)150cm in m
e)1750g in kg

Is there a simple way to work them out so that they can be understood easily and quickly. Thanks in advance.

woow zangetsu i love your explanation. That was pretty cool. Very smart contribution...

Answer 1

It is already simple to work them out.
a) Changing from 2.750m to mm is to multiply by 1000
2.750m * 1000 = 2750 mm

b) Changing from 1.600km to m is to multiply by 1000
1.600km * 1000 = 1600 m

c) Changing from 6.500g to mg is to multiply by 1000
6.500g * 1000 = 6500 mg

d) Changing from 150 cm to m is to divide by 100
150cm / 100 = 1.5m

e) Changing from 1750g to kg is to divide by 1000
1750g * 1000 = 1.750kg

You can do this by just looking at prefix table or just memorize them.
k = 1000 c = 1/100 m = 1/1000

Answer 2

Each of these examples has a conversion factor built into them. Kilo means a thousand. Mili means a thousandth.. So 600 km means 600 times a thousand meters, or 600,000 meters. 1750g in thousands of grams is 1750 divided by 1000, or 1.75 kg. 500 g expressed as thousandths of a gram is 500 times 1000, or 500,000 ,g.

Answer 3

You just have to remember things like:

There are 10mm in 1 cm and 100cm in 1 m thus 1000mm in 1 m;
Kilo means 1000 and so 1000m in 1 km;
milligrams is 10^-3 so there are 1000mg in 1 g;

Answer 4

Yes. Compare the 2 signs. e.g g to kg.
Ask yourself, a gram is (howmuch) to a kg.ans: 1/1000
and so multiply the quantity given in grams by 1/1000.
For simplicity sake, just remember multiply.

Hope this helps=)

Answer 5

For these you just have to remember the conversion units, I find them to be pretty easy but they aren't always for everyone so I'll try to help you out:

10 mm = 1 cm
100 cm = 1m
1000 m = 1 km

1000 grams = 1kg.

Hope that helped :)

Answer 6

multiply by 1000 in cases a), b), c), & e)
and by 100 in case d)
