BfX_Help2(integer) (if you see this information on a web page, click here to go back to the BfX Home page: ) http://www.bfxyz.nl/ Bfx_Help2 informs about unit (e.g. meter to yard) conversions BfX supports Bfx_Help2 also informs which drag functions can be used Other worksheets will elaborate on how to use these features To use BfX_Help2(): create a column with values from 0 … 90 (or so) and then refer to a cell with BfX_Help2(cell to the left) =BfX_Help2(C181) 0 Ballistics for Excel - use =BfX_Help2(i) with i=1,2,3,...96 for more 1 Use BfX_Help(0) for help on BfX functions 2 ===================================BfX_Help2==================================== 3 BfX_Help2 lists available input and output units as well as supported drag 4 functions. Units and functions must be specified in abreviated form, lower case 5 without spaces and other blanks. If no units are specified, the metric standards 6 are used. eg BfX_D("in";740;1000;"yd";0,22;"g7") calculates the drop 7 in [inches] for a bullet of 740 [m/s] (units omitted) at a distance of 8 1000
