Femtosteradians: conversions & definition
Femtosteradians (fsr) represent solid angle. One unit equals 10^-15 sr. A steradian is the solid angle that subtends an area equal to radius squared on a sphere.

Keep the quantity consistent
Choose units that represent the same quantity and preserve the measurement conditions. A scale conversion changes the number and unit together; it does not change the physical amount or improve the accuracy of your measurement.
