Carat (metric)

What is a carat (metric)?

The metric carat (ct) equals exactly 200 milligrams (0.0002 kg).

Origin of the carat (metric)

From Arabic 'qirat' and Greek 'keration', the carob seed once used as a counterweight.

Where it is used

The worldwide standard for gemstone and diamond mass.

When and where it was developed

The metric carat was fixed at 200 mg internationally in 1907.

Deuteron Mass

What is a deuteron mass?

The deuteron mass is about 3.344E-27 kg.

Origin of the deuteron mass

The mass of the deuteron, the nucleus of deuterium (one proton and one neutron).

Where it is used

Nuclear physics and fusion-energy research.

When and where it was developed

Established with the discovery of deuterium by Harold Urey in 1931.

Carat (metric) to Deuteron Mass conversion formula

Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.

The relationship between carats (metric) and deuteron mass:

1 ct = 5.981602e+22 md
1 md = 1.671793e-23 ct

To convert carats (metric) to deuteron mass, multiply the value in carats (metric) by 5.981602e+22. To reverse, multiply deuteron mass by 1.671793e-23.

Step-by-step: convert carats (metric) to deuteron mass

  1. Write down the value in carats (metric) (ct).
  2. Multiply that value by the factor 5.981602e+22.
  3. The product is the equivalent value in deuteron mass (md).
  4. To reverse, multiply the deuteron mass value by 1.671793e-23.

Worked examples

Example 1 — Convert 1 ct to md:
1 × 5.981602e+22 = 5.981602e+22 md

Example 2 — Convert 100 ct to md:
100 × 5.981602e+22 = 5.981602e+24 md

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

One carat (metric) equals one thousand deuteron mass — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 ct × 5.981602e+22 = 5.981602e+22 md

Real-world example — Infrared to visible-spectrum mapping

A 10-carat (metric) thermal infrared wavelength corresponds to a much larger number in deuteron mass, the unit favoured for ultraviolet and visible-light specifications.

10 ct × 5.981602e+22 = 5.981602e+23 md

Real-world example — Mid-micron to nanometer

3 carats (metric) equals 3,000 deuteron mass — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 ct × 5.981602e+22 = 1.794481e+23 md
