Just a quick question on unit conversion..pls help.
-
What is 1g/cm-3 converted to kg/m-3
-
multiply by 1000 if not wrong
eg water density 1g/cm3 ---> 1000kg/m3 -
0.1kg/m^3 ???
-
1000cm is 10m rite??
-
er..yaOriginally posted by snop_coolz:1000cm is 10m rite?? -
google lah, you got tonnes of these conversion webbies that let you type in number and choose unit thenconvert. unless you want the rationale.
basically from grams to kg multiply by 0.001 and to convert from cm3 to m multiply by 100^3 -

1000kg per metre cube
-
Let's see..... 1g/cm3 = (1/1000)kg/(1/100x100x100)m3Originally posted by davidche:What is 1g/cm-3 converted to kg/m-3
= 1000 kg/m3!
-
calculation mistake ah...Originally posted by popikachu:hehe...
1g/cm-3
= 0.001kg/ cm-3
= 0.001kg/ 0.01-3
= 0.01kg/ m-3
yup... thats it...

should be (1/1000)kg/(1/100)m3 nia... cm to metre leh... 1m = 100 cm leh... -
yup, its the same as (0.01)^3.Originally posted by popikachu:[color=red]
??? -
i still dont understand...Originally posted by nightzip:yup, its the same as (0.01)^3.
why is 0.01^3??? -

wha that one too powerful liao dont understand...Originally posted by ditzy: -
Maybe after you get out of uni into the working world.Originally posted by popikachu:wha that one too powerful liao dont understand...

ohh i finally understand liaoOriginally posted by nightzip:yup, its the same as (0.01)^3.
it is the sec 3 maths... if for are is ^2 right? then for volume is ^3 right?
ya finally recall... jia lut... maths fail liao... this year o lvl fail liao... -
I dont know what the -3 is there for??
-
cubic meter.Originally posted by davidche:I dont know what the -3 is there for?? -
so everybody understand already?
-
well like fractions - just convert accordinglyOriginally posted by davidche:What is 1g/cm-3 converted to kg/m-3
1000kg/m^3 = 1g/cm^3 -
nono, not the 3, its the minus sign .
it is supposed to be eg for speed: m s-2 as written in the text book. But why isnt it written as m/s?? they aazre both the same right? -
m s-2 is acceleration lah....where gt sameOriginally posted by davidche:nono, not the 3, its the minus sign .

m s-1 and m/s is the same.... application of indices rule -
then why is acceleration ms-2? and ms-1 speed? i dont find the link?Originally posted by ctstalin:m s-1 and m/s is the same.... application of indices rule
