sorry, this didn't copy correctly : Units = 1000 X OD(420) - [1.75 * OD(550)] / t * v * OD(600)

Evgeny Klimuk

correct formula is Units = 1000 X (OD(420) - [1.75 * OD(550)] )/ t * v * OD(600)

Sorry, to avoid misunderstanding it's better to write like below:

Units = 1000 X (OD(420) - [1.75 * OD(550)]) / (t * v * OD(600))

Yea, same one then. Thanks.
