American <-> Decimal converter. Break even price.

This might help you guys (Excel stuff):

American odds to Decimal odds:

A1=type etc. -126
B1=IF(A1<0;ROUND(1+100/ABS(A1);3);(A1+100)/100)
C1=SUM(1/B1)*100

C1 tells probability%

Decimal odds to American odds:

A2= type etc. 1.43
B2=IF(A2<2;-ROUND(1/(A2-1)*100; 0);IF(A2=2;"Even";A2*100-100))
C2=SUM(1/A2)*100

C1 tells probability%

And if you can estimate probabilities:

A3= type % etc. 56
B3=SUM(100/A3)
C3=IF(B3<2;-ROUND(1/(B3-1)*100; 0);IF(B3=2;"Even";B3*100-100))

B3 tells break even price (decimal)
C3 tells break even price (american)
