I really do not know how to get the answers to these, can you show me on a table form? Thanks
155km to m
2.56Ml to l
155um to mm
1,850nm to mm
1.68Gm to Mm
165pm to nm
2,750u to M
1.5kg to mg
I would like to know how to work these out. Thank you

bobpursley,
You work them out by reading them
155 thousand meters
2.56 million liters
Now many work out with just that.
Some, like
1,859nm to mm are more steps.
1,859 *10^9 meter= 1,859*10^3*10^6meters= 1.859*E 3310 m (noticed I am using E to mean 10^)=1.859E310 millimeter= finally 1.859E6 mm
Give them a shot, and we can critique.

Dear Bob
I don't understand what you mean.
