Units explained

Metric / SI

Microgram

What is a microgram?

A microgram (ug) equals 10^-9 kilogram, or one-millionth of a gram.

Origin of the microgram

From the SI prefix 'micro-' (from Greek 'mikros', small).

Where it is used

Trace nutrients, potent drug doses, and environmental contaminant levels.

When and where it was developed

The micro- prefix was incorporated into the SI in 1960.

Point (1/100 carat)

What is a point (1/100 carat)?

A point equals one-hundredth of a carat, or 2 milligrams.

Origin of the point (1/100 carat)

A subdivision of the metric carat for very small stones.

Where it is used

The diamond trade, for sub-carat stones.

When and where it was developed

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):

1 µg = 0.0005 pt
1 pt = 2000 µg

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.

How to use this converter

Type a value into the calculator. The result in points (1/100 carat) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Point (1/100 carat) to Microgram converter for the reverse direction.

Step-by-step: convert micrograms to points (1/100 carat)

  1. Write down the value in micrograms (µg).
  2. Multiply that value by the factor 0.0005.
  3. The product is the equivalent value in points (1/100 carat) (pt).
  4. 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
