Covert g/ml to kg/m^3
« on: December 04, 2008, 02:17:19 AM »
I'm not sure what I"m doing wrong, but I keep screwing this up. 

0.600 g/ml   ====>  kg/m^3



1kg=1000g
cm^3 = ml
100cm = M

How do I do this?  I'm sure its simple but I'm apparently missing something?

1) Convert g to kg first and what should you do to the 0.600?
2) 1 cm3 = 1 ml  = ? m3
No matters what results are waiting for us, it's nothing but the DESTINY!!!!!!!!!!!!

So you have :0.6g/ml

This is 0.0006kg per ml
or 0.06 kg per 1ml (or 100cm^3)
since 100cm =m
this means you have 0.06kg/m^3

another way of thinking of this is:
(1g/1ml)10 = (1kg/1m^3)
since
1g  x 1000 = 1kg
1ml x 1000 = 10m^3
which (when diving top and bottom of LHS)
1g  = 1kg
1ml = 10m
so when converting g/ml into kg/M^3 always divide by 10
or 1g/ml = 10g/10ml = 100g/100ml = 1000g/1000ml = 1kg/10m^3

(Remember, case is important M is reserved for Molar, K is reserved for Kelvin)

You are very, very wrong.

This is 0.0006kg per ml
or 0.06 kg per 1ml (or 100cm^3)

That means 0.0006kg=0.06kg.

No. 1 cubic meter is NOT 100 cubic centimeters.

Rest of the post deleted, but it wasn't getting any better :(

Painfully, painfully wrong  :o  :'( :'(
