1/24 scale figure question

Besides figures that are listed as 1/24 scale, or 1/25 scale, what would be the equivalent in millimeters for military miniatures?  I want to model the Airfix 1/24 scale Hurricane, and I want aircrew for a sense of scale, and to add a little visual interest.  There may not be an exact match for me to choose from in this scale as a pilot figure, but I can press-gang a scale figure that has the correct proportions into the RAF, circa 1940.

Thanks to all who reply.

With best regards,

Steve Mack
