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.

Jupiter Mass

What is a jupiter mass?

The Jupiter mass (M(J)) is about 1.898E27 kg.

Origin of the jupiter mass

The mass of Jupiter, the standard unit for gas giants and exoplanets.

Where it is used

Exoplanet characterization and planetary science.

When and where it was developed

Refined through telescopic and spacecraft observations of Jupiter.

Carat (metric) to Jupiter 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 jupiter mass:

1 ct = 1.053669e-31 MJ

1 MJ = 9.49065e+30 ct

To convert carats (metric) to jupiter mass, multiply the value in carats (metric) by 1.053669e-31. To reverse, multiply jupiter mass by 9.49065e+30.

How to use this converter

Type a value into the calculator. The result in jupiter mass updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Jupiter Mass to Carat (metric) converter for the reverse direction.

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

Write down the value in carats (metric) (ct).
Multiply that value by the factor 1.053669e-31.
The product is the equivalent value in jupiter mass (MJ).
To reverse, multiply the jupiter mass value by 9.49065e+30.

Worked examples

Example 1 — Convert 1 ct to MJ:
1 × 1.053669e-31 = 1.053669e-31 MJ

Example 2 — Convert 100 ct to MJ:
100 × 1.053669e-31 = 1.053669e-29 MJ

Real-world example — Paper and film thicknesses

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

3 ct × 1.053669e-31 = 3.161006e-31 MJ

Real-world example — Plastic-film thickness alternates

A 150-carat (metric) plastic film converts cleanly to jupiter mass — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.

150 ct × 1.053669e-31 = 1.580503e-29 MJ

Real-world example — Hair-width scale measurements

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

70 ct × 1.053669e-31 = 7.37568e-30 MJ
