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.

Metric / SI

Attogram

What is a attogram?

An attogram (ag) equals 10^-21 kilogram.

Origin of the attogram

From the SI prefix 'atto-' (from Danish 'atten', eighteen).

Where it is used

Frontier nanoscience and single-molecule mass detection.

When and where it was developed

The atto- prefix was adopted by the CGPM in 1975.

Point (1/100 carat) to Attogram conversion formula

The relationship between points (1/100 carat) and attograms:

1 pt = 2e+15 ag
1 ag = 5e-16 pt

To convert points (1/100 carat) to attograms, multiply the value in points (1/100 carat) by 2e+15. To reverse, multiply attograms by 5e-16.

How to use this converter

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

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

  1. Write down the value in points (1/100 carat) (pt).
  2. Multiply that value by the factor 2e+15.
  3. The product is the equivalent value in attograms (ag).
  4. To reverse, multiply the attogram value by 5e-16.

Worked examples

Example 1 — Convert 1 pt to ag:
1 × 2e+15 = 2e+15 ag

Example 2 — Convert 100 pt to ag:
100 × 2e+15 = 2e+17 ag

Real-world example — Infrared to visible-spectrum mapping

A 10-point (1/100 carat) thermal infrared wavelength corresponds to a much larger number in attograms, the unit favoured for ultraviolet and visible-light specifications.

10 pt × 2e+15 = 2e+16 ag

Real-world example — Mid-micron to nanometer

3 points (1/100 carat) equals 3,000 attograms — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 pt × 2e+15 = 6e+15 ag

Real-world example — From microns to sub-micron features

One point (1/100 carat) equals one thousand attograms — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 pt × 2e+15 = 2e+15 ag
