Units explained
Planck Mass
The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.
Introduced by Max Planck in 1899 as part of a system of natural units.
Theoretical physics and quantum-gravity research.
Defined by Planck in 1899 from fundamental constants.
Carat (metric)
The metric carat (ct) equals exactly 200 milligrams (0.0002 kg).
From Arabic 'qirat' and Greek 'keration', the carob seed once used as a counterweight.
The worldwide standard for gemstone and diamond mass.
The metric carat was fixed at 200 mg internationally in 1907.
Planck Mass to Carat (metric) 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 planck mass and carats (metric):
To convert planck mass to carats (metric), multiply the value in planck mass by 0.0001088355. To reverse, multiply carats (metric) by 9188.1784895553.

Step-by-step: convert planck mass to carats (metric)
- Write down the value in planck mass (mP).
- Multiply that value by the factor 0.0001088355.
- The product is the equivalent value in carats (metric) (ct).
- To reverse, multiply the carat (metric) value by 9188.1784895553.
Worked examples
Example 1 — Convert 1 mP to ct:
1 × 0.0001088355 = 0.0001088355 ct
Example 2 — Convert 100 mP to ct:
100 × 0.0001088355 = 0.01088355 ct
Real-world example — Sub-visible-light wavelength
500 planck mass (the green-yellow visible band) equals 0.5 carats (metric) — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 mP × 0.0001088355 = 0.05441775 ct
Real-world example — Spanning sub-micron to micron scale
Crossing from planck mass to carats (metric) is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 planck mass translates to a much more compact value in carats (metric) that fits the scale of biological cells and process nodes.
1000 mP × 0.0001088355 = 0.1088355 ct
