Units explained
Metric Ton
The metric ton (t) equals exactly 1,000 kilograms; it is also called the tonne.
From 'tun', a large medieval cask; 'metric' distinguishes it from imperial tons.
The global standard for trade, freight, and heavy industry.
Recognized internationally with the spread of the metric system in the late 19th century.
Carat (metric)
The metric carat (ct) equals exactly 200 milligrams (0.0002 kg).
From Arabic 'qirat' and Greek 'keration', the carob seed once used as a counterweight.
The worldwide standard for gemstone and diamond mass.
The metric carat was fixed at 200 mg internationally in 1907.
Metric Ton to Carat (metric) conversion formula
The relationship between metric tons and carats (metric):
To convert metric tons to carats (metric), multiply the value in metric tons by 5000000. To reverse, multiply carats (metric) by 2e-7.

Step-by-step: convert metric tons to carats (metric)
- Write down the value in metric tons (t).
- Multiply that value by the factor 5000000.
- The product is the equivalent value in carats (metric) (ct).
- To reverse, multiply the carat (metric) value by 2e-7.
Worked examples
Example 1 — Convert 1 t to ct:
1 × 5000000 = 5000000 ct
Example 2 — Convert 100 t to ct:
100 × 5000000 = 5e+8 ct
Real-world example — Geographic to fiber-optic scale
One metric ton equals one billion carats (metric). This conversion appears in fiber-optic specifications, where total link length is given in metric tons but signal attenuation depends on micro-scale variations along the fiber.
1 t × 5000000 = 5000000 ct
Real-world example — Long-haul to feature-scale
One metric ton equals one billion carats (metric) — useful in fiber-optic engineering, where total cable length is given in the larger unit but feature-level attenuation depends on micro-scale variations.
1 t × 5000000 = 5000000 ct
