I need help on this one problem, because there so many conversions I get so confused

An average man requires about 2.00 mg of vitamin B2 per day. How many pounds of cheese would a man have to eat per day if this were his only sources of vitamin B2 and if the cheese contained 5.5 µg of vitamin B2 per gram of cheese?

Please leave the answer in significant answer and explain to me what to do also thanks
 
5.5 µg of vitamin B2 = 5.5x10^-6 g B2 / 1 g cheese
2.00 mg B2 = 2.00 x 10^-3 g of vitamin B2
2.00x10^-3 / 5.5x10^-6 / 1 g cheese = 3.64x10^2 g cheese
360 g cheese (2 s.f.)
