Hi.
I been looking at your calcs for a while now and I think theres deffo something wrong with calc 2 somewhere.
I cant put my finger on it just yet as I dont have all the info i.e the original calc/question.
Anything with a - in fornt must be divided to gain the base unit unit i.e 10-6 would be 10,000,000 as a base unit - a micro unit.
Cheers.
ElectricAl beat me to it.
