Proton Mass

What is a proton mass?

The proton rest mass is about 1.6726E-27 kg.

Origin of the proton mass

The mass of the proton, the positively charged nucleon.

Where it is used

Nuclear and particle physics, and chemistry.

When and where it was developed

Quantified after Rutherford identified the proton around 1917-1920.

Troy & Apothecary

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.

Proton Mass to Point (1/100 carat) 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 proton mass and points (1/100 carat):

1 mp = 8.363116e-22 pt
1 pt = 1.195727e+21 mp

To convert proton mass to points (1/100 carat), multiply the value in proton mass by 8.363116e-22. To reverse, multiply points (1/100 carat) by 1.195727e+21.

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 Proton Mass converter for the reverse direction.

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

  1. Write down the value in proton mass (mp).
  2. Multiply that value by the factor 8.363116e-22.
  3. The product is the equivalent value in points (1/100 carat) (pt).
  4. To reverse, multiply the point (1/100 carat) value by 1.195727e+21.

Worked examples

Example 1 — Convert 1 mp to pt:
1 × 8.363116e-22 = 8.363116e-22 pt

Example 2 — Convert 100 mp to pt:
100 × 8.363116e-22 = 8.363116e-20 pt

Real-world example — Spanning sub-micron to micron scale

Crossing from proton mass to points (1/100 carat) is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 proton mass translates to a much more compact value in points (1/100 carat) that fits the scale of biological cells and process nodes.

1000 mp × 8.363116e-22 = 8.363116e-19 pt

Real-world example — Sub-visible-light wavelength

500 proton mass (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 mp × 8.363116e-22 = 4.181558e-19 pt
