【Estimating on Fermi and something approximate】

《Estimating a scale of market on jeans》

The author, ...so the scale of market on jeans is equal to about 0.6% on the GDP, and is equal to a thousand of Ochiai who is a professional Japanese baseball player. By the way how about the whole world?

An annual salary of Ochiai was three hundred million and both the author and his friend love baseball.

His friend, Mmmm...the whole world? There is a cultural sphere where no one puts on jeans, so the number of jeans they buy a year become less. One to ten people buy a pair or two pairs jeans a year?
