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.
Point (1/100 carat)
A point equals one-hundredth of a carat, or 2 milligrams.
A subdivision of the metric carat for very small stones.
The diamond trade, for sub-carat stones.
Adopted alongside the metric carat in the 20th-century gem trade.
Microgram to Point (1/100 carat) conversion formula
The relationship between micrograms and points (1/100 carat):
To convert micrograms to points (1/100 carat), multiply the value in micrograms by 0.0005. To reverse, multiply points (1/100 carat) by 2000.

Step-by-step: convert micrograms to points (1/100 carat)
- Write down the value in micrograms (µg).
- Multiply that value by the factor 0.0005.
- The product is the equivalent value in points (1/100 carat) (pt).
- To reverse, multiply the point (1/100 carat) value by 2000.
Worked examples
Example 1 — Convert 1 µg to pt:
1 × 0.0005 = 0.0005 pt
Example 2 — Convert 100 µg to pt:
100 × 0.0005 = 0.05 pt
Real-world example — Spanning sub-micron to micron scale
Crossing from micrograms to points (1/100 carat) is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 micrograms translates to a much more compact value in points (1/100 carat) that fits the scale of biological cells and process nodes.
1000 µg × 0.0005 = 0.5 pt
Real-world example — Sub-visible-light wavelength
500 micrograms (the green-yellow visible band) equals 0.5 points (1/100 carat) — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 µg × 0.0005 = 0.25 pt
