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

Exagram

What is a exagram?

An exagram (Eg) equals 10^15 kilograms, or one quintillion grams.

Origin of the exagram

From the SI prefix 'exa-' (from Greek 'hex', six, denoting the sixth power of 1000).

Where it is used

Confined to planetary- and atmospheric-scale mass discussions; never used in daily measurement.

When and where it was developed

The exa- prefix was adopted by the General Conference on Weights and Measures (CGPM) in 1975.

Point (1/100 carat) to Exagram conversion formula

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

1 pt = 2e-21 Eg
1 Eg = 5e+20 pt

To convert points (1/100 carat) to exagrams, multiply the value in points (1/100 carat) by 2e-21. To reverse, multiply exagrams by 5e+20.

How to use this converter

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

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

  1. Write down the value in points (1/100 carat) (pt).
  2. Multiply that value by the factor 2e-21.
  3. The product is the equivalent value in exagrams (Eg).
  4. To reverse, multiply the exagram value by 5e+20.

Worked examples

Example 1 — Convert 1 pt to Eg:
1 × 2e-21 = 2e-21 Eg

Example 2 — Convert 100 pt to Eg:
100 × 2e-21 = 2e-19 Eg

Real-world example — Hair-width scale measurements

A 70-point (1/100 carat) measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like exagrams for direct comparison across supplier datasheets.

70 pt × 2e-21 = 1.4e-19 Eg

Real-world example — Paper and film thicknesses

At the thickness of office paper (roughly 3 points (1/100 carat)), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.

3 pt × 2e-21 = 6e-21 Eg

Real-world example — Plastic-film thickness alternates

A 150-point (1/100 carat) plastic film converts cleanly to exagrams — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.

150 pt × 2e-21 = 3e-19 Eg
