AI Thread Summary
The discussion centers on converting the scientific notation 1.95e7m, which represents 1.95 times 10 to the power of 7 meters. Participants clarify that both "e" and "E" in this context denote exponentiation, specifically a power of ten, and are interchangeable. There is a distinction made between "e" as Euler's number and "E" as used in scientific notation, emphasizing that in calculators and spreadsheets, "e" or "E" indicates an exponent. It is recommended to use a capital "E" to avoid confusion with Euler's number. Overall, the consensus is that 1.95e7m equals 19,500,000 meters.

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.)
 
1.95e7 is the same as 1.95x10^7?
 
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. :smile: )
 
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".
