Human MPG biking and walking

[VNelson]

I thought it would be interesting to calculate the 'mpg' of walking and biking...so here goes.

A gallon of gas contains about 31,000 Kilocalories (Kc).

An average person expends 100 Kc to walk one mile.

An average person bicycling leisurely (9 mph) expends about 23 Kc per mile.

So, if he/she could get all the needed calories from a gallon of gas (ugh), he/she

would get:

310 mpg walking (31000/100), and

1348 mpg bicycling (31000/23).

Since you can't get your calories from gas, what would be the cost in
Snicker's Bar Equivalents (my measure) for a 'gallon' of gas?

A Snicker's bar has 280 Kc and costs about 60 cents. So:

31000/280*.60= $66.42 per 'gallon'.
