| 1419686 | 2016-04-28 07:24:00 | Hi Team I am using a dedicated website calculator to convert a particular magnetic field value to and from different magnetic parameters. I am temporarily stumped by values such as 5.262e-4 and 5.262e-8, or 5262e+4 but my best guess is that they refer to the number of zeros that should follow, but then the option of plus or minus signs sent me back to the starting line!!! Can anybody clarify this for me please? Cheers Billy 8-{) :confused: |

For sure this value cannot go any other way. Cheers Billy 8-{) |
