Usage: convert_bcf number
This command will convert a BCF rating into ELO and USCF ratings. All three values will be displayed to you. The conversion formulas are:
| USCF | = | ELO + 100 |
| BCF | = | (ELO - 600)/8 |
BCF ratings are the official ratings of the British Chess Federation. USCF ratings are the official ratings of the United States Chess Federation. ELO ratings often used in international competition.
Server ratings are, of course, something entirely different. There is no exact way at present to convert server ratings into equivalent official ratings. For server rating information, see "rating" or "glicko".
