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.

Point (1/100 carat) to Carat (metric) conversion formula

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

1 pt = 0.01 ct
1 ct = 100 pt

To convert points (1/100 carat) to carats (metric), multiply the value in points (1/100 carat) by 0.01. To reverse, multiply carats (metric) by 100.

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

  1. Write down the value in points (1/100 carat) (pt).
  2. Multiply that value by the factor 0.01.
  3. The product is the equivalent value in carats (metric) (ct).
  4. To reverse, multiply the carat (metric) value by 100.

Worked examples

Example 1 — Convert 1 pt to ct:
1 × 0.01 = 0.01 ct

Example 2 — Convert 100 pt to ct:
100 × 0.01 = 1 ct

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 carats (metric) for direct comparison across supplier datasheets.

70 pt × 0.01 = 0.7 ct

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 × 0.01 = 0.03 ct

Real-world example — Plastic-film thickness alternates

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

150 pt × 0.01 = 1.5 ct
