Convert from palmo [Portuguese] to bicron

Unit Definition (palmo [Portuguese])
The palmo is a traditional unit of distance in Spain and Portugal. The Portuguese palmo equals 0.1 braça or about 22.0 centimeters (8.66 inches). These units are based on the width of a person's outstretched hand, from the tip of the thumb to the tip of the little finger, a definition identical to that of the English span.

Unit Definition (bicron)
The Bicron is an obsolete metric unit of distance, which was defined as 10e-12 meter or 10e-6 micron. This distance is now called a picometer or picometre (pm). The name is a reference to the double prefix "micro-micron".
