How many steps does the average person make in a day, and how many times does a person walk the circumference of the earth in a lifetime?

kerry8888

some sites say about 3000 to 5000 steps per day http://www.healthpartners.com/Menu/0,1598,8659,00.html others say about 8000 to 10000 per day http://www.mkmg.com/articles/footprobs.htm as far as the round the world thing goes - ill leave it those more mathematically inclined.... May 15 03, 4:41 AM

There are far better mathematicians on this site than me, but here goes anyway: The site below gives the circumference of the Earth at the equator as 24,901.55 miles. As there are 5,280 feet in a mile, this equates to 131,480,184 feet. Given an average length of pace of 2.5 feet (various sites) and rounding down to 2 feet to allow for times when we are either very old or very young and take shorter paces, this equates to 65,740,092 paces round the Earth. Assuming a lifespan of 75 years, ignoring leap years, and taking 5,000 as a conservative estimate for the average number of steps in a day from Kerry's figures above (to allow for being very old and very young when we may not take so many steps in a day) we come to a figure of 136,875,000 paces in a lifetime. Divide this by the number of paces required to go round the Earth, and we come to a figure of 2.08. So, allowing for all the assumptions, roundings and guesstimations above, the 'average' person will walk round the world twice in his or her lifetime. http://geography.about.com/library/faq/blqzcircumference.htm May 15 03, 7:23 PM
