Speaking about calories and nutrition - and I apologize if this is a bit off topic, but this has been bothering me awhile - but why is it that when you compare the nutritional guide (in canada anyways) on a bottle of diet pepsi and a bottle of water, they are the same???

i have 65 kilograms...........

so i have 65*2.2=143 pounds

Just FYI even though this is an old thread.
Google has a built in converter for currency/mass/length etc
Just type in something like "1oz in grams" or "5 miles in kilometers" and it will give you the answer in an instant! its easy and comes in handy.
