Propeller block calculators 

The following calculators are useful when carving a propeller using the style of block illustrated above. Enter the values in the shaded boxes. The other values will update as soon as you click in a new box or press the button. The calculators work for either English or metric values. Fractional equivalents (to the nearest 1/32nd) are computed for convenience. The calculators also compute the shoulder radius percentage, pitch:diameter ratio and maximum blade chord. These may be useful when designing your own propellers.
