NORMAN, Okla. -
April Steiner, competing unattached, recorded the top pole vault mark in the world so far this year, clearing a height of 15 feet and 5.25 inches (4.63 meters).  Mike Robertson, competing for Nike, set a meet record in the men's discus with a throw of 212-2 (64.66).

4.63 meters is 15-2... but anyways, this post was about Chelsey! Make a seperate post for April! Congrats to both by the way! I can't wait to see how high they are jumping a month from now!!

At the TX Relays, Chelsea had one warmup jump that was probably in the 15'6" range. She looked pretty dang impressive and ready to jump well above 4.60.

Actually, the topic of the post was for both vaulters. Nice jumps regardless
by these two outstanding vaulters.


Where did you come up with 15'-2" as the imperial measure for 4.63??
My "Big Gold Book" shows 4.63 is 15'-2.25".. I doubt this book is wrong. We (officials) have been using it for years.

When you measure imperially, do you round down a cm when converting to metric? For example if you measure an imperially to hit 19'0 1/4" the metric conversion would be 5.79, however, if you measured it metrically as 5.80 then it would convert to 19'0 1/4". A ref told me this once but I've always had doubts about that.

OR, on the T&F News message board a few years ago, someone stated that in the conversion book that 5.80 vertically converts to 19'0 1/4" but if you measure it horizontally it's 19'0 1/2". I have no idea why.

When I measure for collegiate or elite heights, the measuring device or laser is set to metric. I go to the T&F News "gold book" to get any imperial value conversion if requested.

I am aware of the difference you point out as some time ago I was puzzled as to why there was a separate set of tables for the vertical jumps and the horizontal jumps in back then the "little red" book, "little blue" book, "little gold" book, "Big Red" book, "Big Green" book and of course todays "Big Gold" book.

An explanation was in a topic called the Introduction to the tables in the front of these books. It's is known as the statisticians' challenge.

One thing the book says, is the tables are designed to convert from metric to the imperial system. I follow that and never try to convert the other way using this book. If I measure in imperial as I do for high school (NFHS) meets, I'll not state a metric equivalent to anyone.

There are 2.54 centimeters in one imperial inch exactly.

The direction does not matter.

Memorize it.

It actually does for track and field. I believe what is listed in the Big book of whatever color is what the IAAF uses. You can see an example of this here: http://www.usatf.org/statistics/calcula ... nversions/ if you type 5.80 for the pole vault and then for the long jump.

5.8 m = 228.34645.... inches = 19' 0.346..."

The program on the USATF web page is challenged when rounding.

There will be a test on Friday.

Vaultref,
I knew that 4.63 was 15-2 and some change, but i just figured that the .25 was not necessary when all i was saying was the article was way off by giving the translation of 4.63 as 15-5.25, which is a whole three inches off and a huge difference when it comes to the pole vault.

I also have a nice little conversion book that I use when i need it, but i generally have most of the heights remembered from personal use anywhere between 4.30 and 6.00 meters... i guess it was just a case of me being lazy and not typing the .25 after i put 15-2...

But that is how track and field works. It doesn't matter what is mathematically accurate.
