Unit conversion

Postby bprku » Fri May 08, 2009 9:27 am

Can anyone help me by converting daphnia/L into Daphnia/square meter.
for example If I have 20 Daphnua/L, then how may it will be in square meter:

20 Daphnia/L = ?? daphnia/m2.

A liter is 1/100th of a square meter.
Generally speaking, the more people talk about "being saved," the further away they actually are from true salvation.

A litre is a volume. A square metre is a surface.
There are 1000 Litres in a cubic meter.
If you want to know how many daphnia there are below 1 square meter of surface of sea/fish bowl/lake water you first have to calculate the volume under that surface by multiplying it by the depth of the water.

Oh goodness, I just realized I converted to square meters and not cubic meters! Goodness, I'm going to chalk that up to a finals-induced brain fart. Hopefully I won't do something that silly on a test! :p
