Scientific units of measure utilized by Reciprocal Net sample records conform to the standard CIF units (as defined by the Crystallographic Information File format specification), except for temperatures, which CIF specifies be in degrees Kelvin but Reciprocal Net stores in degrees Celsius.
Specifically, unit cell axis lengths are stored in Angstroms, unit cell inter-axis angles are stored in degrees, unit cell volume is stored in cubic Angstroms, density is stored in grams per cubic centimeter, chemical formula weight is stored in grams per mole, and temperature is stored in degrees Celsius.
