Convert from pace [Roman] to angstrom

Unit Definition (pace [Roman])
A pace (or double-pace) is a measure of distance used by Ancient Rome. It is the measure of a full stride from the position of the heel when it is raised from the ground to the point he heel is set down again at the end of the step. In Rome this was standardized as about five Roman feet or 58.1 English inches.

Unit Definition (angstrom)
The Angstrom is a metric unit of length, equal to 0.1 nanometer or 10e-10 meter. Angstroms are most often used to measure the wavelength of light and are commonly used by chemists and physicists in the field of spectroscopy. One of the pioneers of spectroscopy was the Swedish physicist Anders Jon Ångström (1814-1874), after whom the unit is named.
