Units explained
Microgram
A microgram (ug) equals 10^-9 kilogram, or one-millionth of a gram.
From the SI prefix 'micro-' (from Greek 'mikros', small).
Trace nutrients, potent drug doses, and environmental contaminant levels.
The micro- prefix was incorporated into the SI in 1960.
Poundal
The poundal (pdl) is the FPS absolute unit of force; its mass-equivalent on this scale is about 0.0141 kg.
Defined in the foot-pound-second absolute system in the late 19th century.
Early 20th-century physics and engineering.
Introduced in the absolute FPS system as an alternative to gravitational units.

Worked examples
Example 1 — Convert 1 µg to pdl:
1 × 7.098885e-8 = 7.098885e-8 pdl
Example 2 — Convert 100 µg to pdl:
100 × 7.098885e-8 = 7.098885e-6 pdl
Real-world example — Sub-micron to millimeter
500,000 micrograms converts to a small everyday quantity in poundals — useful when relating optical-wavelength specifications to physical mounting hardware.
500000 µg × 7.098885e-8 = 0.0354944241 pdl
Real-world example — From wavelengths to millimeter-scale objects
A value of one million micrograms sounds vast at the atomic scale but converts to a small everyday quantity in poundals — useful when relating optical-wavelength specifications to physical mounting hardware.
1000000 µg × 7.098885e-8 = 0.0709888482 pdl
