Can someone help? It may seem elementary, but I have an application identifying a radius of 1.95e7m. What does the 1.95e7m convert to?

1.95e7 means $1.95 \times 10^7$. (And m = meters.)

 

[Bcisewski]

1.95e7 is the same as 1.95x10^7?

 

[Integral]

Yes, they are the same.

hey guys but isn't "e" and "E" different. for example e1 = 2.718 and E1 = 10. if you want it to be the same as 1.95x10^7 then i suggest you use a capital E so as not to confuse.

I've never seen it used that way. I've always seen 1.95e7 = 1.95E7 = $1.95 \times 10^7$. In this context, I believe that e or E just stands for "exponent". (Personally, I always use E. )

Generally something in the form of $A.BCeX$, where X is an integer, is considered to be $A.BC\times{10^{X}}$, although this is not a definite rule. It is better to write it in the latter form to avoid confusion.

It's a calculator based tradition. Calculator's, especially your early LED's, weren't very good at displaying scientific notation the way you do on paper. It's displayed 1.95e7 or 1.95E7 on a spread sheet, as well, for the same reason.

As DocAl, Integral, Sirus, and BobG pointed out, whenever $\text{e\ \or\ \E}$ appear in this context (on a calculator or computer) it refers to a power of ten. It should not be confused with $e$, Euler's number, the irrational constant. Just thought I'd clarify that.

ok i understand what you guys are saying, i just made the point because on my calculator the two of them are two different e's. the exponent is "E" and the constant is "e".
