## Homework Statement

I am given some measurements and I am supposed to express them as standard SI units. I can't find any examples of this done online or extra practice exercises to help me. I am probably googling the wrong words.

I have been out of school for quite a while and I don't know what some of the abbreviations stand for, and a lot of letters seem to double up in physics.

105km

57mm

6.67x10

^{-11}cm

6x10

^{27}grams

9 grams per cubic centimetre

100 km h

^{-1}

5 nN

10μW

5Gm

I don't know what G, or μ or h (hour?) stand for here.

## Homework Equations

3. The Attempt at a Solution [/B]

**105km -**105 x 10

^{-3}m - This is wrong. It should be 1.05x 10

^{5}m (But I think I understand why)

**57mm -**5.7 x 10

^{-2}m

**6.67x10**- 6.67x10

^{-11}cm^{-12}m - Wrong 6.67x10

^{-13}m (because there are 2 zeros in 100, not one, wupps)

**6x10**6x10

^{27}grams^{24}kg

**9 grams per cubic centimetre**- ?

**100 km h**-? I assume h is hour.

^{-1}**- ?**

5 nN

5 nN

**- ?**

10μW

10μW

**- ?**

5Gm

5Gm

I already know the answers, clues about how to get them for myself would be brilliant, thanks everyone.
