How much do the most expensive football players in the world cost per kg?

June 25, 2009

Ricardo Izecson dos Santos Leite (born April 22, 1982 in Brasília, Brazil), simply known as Kaká, is a Brazilian footballer who plays as a midfielder.

picture-kaka10Last week it was announced that Real Madrid  had paid Kaka’s current club, AC Milan €65 million ($114.5m) for the soccer player.

This is the second highest payment in football history as  the record transfer deal was set by Zinedine Zidane when he joined Madrid from Juventus for €75m ( $ 132.1 m) in 2001. (Sydney Morning Herald 10 June 2009 #mce_temp_url# )





man_throwing_money               Kaka Weight =  73 kg

               Zidane weight = 78 kg.

          Now mathspigs you have enough information to calculate how much these soccer players are worth per kilo. 

           You can use a table, a picture graph or a bar graph to compare the costs of these footballers per kilo with other products available on the market today. Don’t forget mathspigs football players are bought and sold like commodities so this is a reasonable comparison to make:

platinum = $46,700 per kilo

  gold = $37,500 per kilo

 silver = $ 560 per kilostanding on money

Tic Tacs = $ 44.44 per kilo (Confectionery costs from grocery.bestpricedirectory #mce_temp_url#

Freddo Frogs = $19.95 per kilo

Meanwhile you can easily work out if Kaka is worth his weight in gold. Or, to put it another way, how many kilo of gold would Real Madrid need if they were to pay for Kaka in gold bullion? Australia actually produces 1 kg gold ingots or bars. So how many gold bars would Kaka cost?

As one of our sayings in English is ‘It cost me an arm and a leg’ you can also work out how much a ‘very upmarket’ arm and leg might cost.

 To do this maths pigs you need to know the approximate weight of a human arm and leg.

According to Wikianswers a human arm weighs approx 3.3 kg. arm

While according to that great source of information Wii Fit your legs make up 40% of your body weight. So one leg is 20 % of a person’s body weight. You now have enough information to calculate how much an arm & a leg is worth in World Soccer.

Go to it mathspigs.
