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.

Biblical / Ancient

Lepton (Biblical Roman)

What is a lepton (biblical roman)?

The lepton was the smallest coin of New Testament times, about 0.03 gram in this scale.

Origin of the lepton (biblical roman)

From Greek 'lepton', meaning small or thin.

Where it is used

Biblical references to the smallest possible sums.

When and where it was developed

The lowest-value coin in circulation in first-century Judea.

Carat (metric) to Lepton (Biblical Roman) 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 leptons (biblical roman):

1 ct = 6.6493561761 lepton
1 lepton = 0.1503905 ct

To convert carats (metric) to leptons (biblical roman), multiply the value in carats (metric) by 6.6493561761. To reverse, multiply leptons (biblical roman) by 0.1503905.

How to use this converter

Type a value into the calculator. The result in leptons (biblical roman) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Lepton (Biblical Roman) to Carat (metric) converter for the reverse direction.

Step-by-step: convert carats (metric) to leptons (biblical roman)

  1. Write down the value in carats (metric) (ct).
  2. Multiply that value by the factor 6.6493561761.
  3. The product is the equivalent value in leptons (biblical roman) (lepton).
  4. To reverse, multiply the lepton (biblical roman) value by 0.1503905.

Worked examples

Example 1 — Convert 1 ct to lepton:
1 × 6.6493561761 = 6.6493561761 lepton

Example 2 — Convert 100 ct to lepton:
100 × 6.6493561761 = 664.9356176088 lepton

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 × 6.6493561761 = 19.9480685283 lepton

Real-world example — Plastic-film thickness alternates

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

150 ct × 6.6493561761 = 997.4034264132 lepton

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 leptons (biblical roman) for direct comparison across supplier datasheets.

70 ct × 6.6493561761 = 465.4549323262 lepton
