# Stones to Carats (st to ct) Source: https://www.unitconvertercalculator.com/weight/stones-to-carats/ **1 st = 31751.4659 ct** One stone equals approximately 31,751 carats. The stone, at 14 pounds, is the British unit for measuring people, while the carat, at 0.2 grams, measures gemstones. Converting between them provides a vivid illustration: an 11-stone person would 'weigh' about 349,267 carats, roughly the equivalent of 350,000 one-carat diamonds. ## Formula Apply the conversion factor ## Conversion Table | Stones (st) | Carats (ct) | |---|---| | 0.01 st | 317.514659 ct | | 0.05 st | 1587.573295 ct | | 0.1 st | 3175.14659 ct | | 0.25 st | 7937.866475 ct | | 0.5 st | 15875.73295 ct | | 1 st | 31751.4659 ct | | 2 st | 63502.9318 ct | | 5 st | 158757.3295 ct | | 8 st | 254011.7272 ct | | 10 st | 317514.659 ct | | 14 st | 444520.5226 ct | | 20 st | 635029.318 ct | | 25 st | 793786.6475 ct | | 50 st | 1587573.295 ct | ## Units ### Stone (st) A British unit of mass equal to 14 pounds or approximately 6.35 kilograms. Commonly used in the UK and Ireland for body weight. ### Carat (ct) A carat is a unit of mass equal to exactly 200 milligrams (0.2 grams), used for measuring gemstones and pearls. Adopted internationally in 1907 by the Fourth General Conference on Weights and Measures. ## Background No practical scenario requires this conversion. It exists for mathematical completeness and for the occasional entertaining comparison between body weight and gemstone weight. ## Good to Know The stone and carat both relate to the human body but in opposite ways. The stone measures the person's mass; the carat adorns the person with precious stones. One measures what you weigh; the other measures what you wear. Their conversion factor of 31,751 captures the enormous gap between the scale of human bodies and the scale of human adornment. ## FAQ ### How many carats are in one stone? One stone equals approximately 31,751 carats. This is 6,350 grams divided by 0.2 grams per carat. ### Is this conversion ever used? No. Body weight and gemstone weight never need direct comparison in any commercial or scientific context. ### How do I convert stones to carats? Multiply stones by 31,751. For example, 10 stones equals about 317,515 carats. ## Non-Frequently Asked Questions ### If I weigh 12 stone, how much am I worth in diamonds? At 12 stone (381,018 carats) and an average gem diamond price of $5,000 per carat, you would be worth approximately 1.9 billion dollars if made entirely of diamond. This exceeds the GDP of several small nations and would make you the most valuable object on the planet. Alas, human tissue trades at considerably lower rates. ### Has anyone ever weighed a gemstone collection in stones? The world's largest gem collections weigh far less than one stone. The entire British Crown Jewels collection, including every diamond, ruby, sapphire, and emerald, weighs a few kilograms at most, well under one stone. Gemstones are valuable precisely because they are rare and small. ### Which is more romantic: your weight in carats or in stones? Carats sound far more romantic, even though the number is much larger. 'You are worth 350,000 carats to me' is a declaration of extraordinary value. 'You are 11 stone to me' is a factual observation about mass that will not appear on any greeting card, regardless of its mathematical equivalence. ## Related Articles - [Why We Measure: The Deepest Urge in Human Civilisation](https://www.unitconvertercalculator.com/blog/why-we-measure) - [The Map Is Not the Territory: Why Every Measurement Is Wrong](https://www.unitconvertercalculator.com/blog/the-map-is-not-the-territory) - [Zero: The Most Dangerous Number in Measurement](https://www.unitconvertercalculator.com/blog/zero-the-most-dangerous-number-in-measurement) - [The Kilogram Problem: The Object That Was Its Own Definition](https://www.unitconvertercalculator.com/blog/the-kilogram-problem) - [The Body as a Ruler: Every Measurement Unit That Came From Us](https://www.unitconvertercalculator.com/blog/the-body-as-a-ruler) - [Why Your Recipe Is Lying to You: The Chaos of Cooking Measurements](https://www.unitconvertercalculator.com/blog/why-recipe-measurements-are-unreliable) - [15 Obscure Measurement Units You've Never Heard Of (But Still Need)](https://www.unitconvertercalculator.com/blog/obscure-measurement-units-guide) - [When Measurements Go Wrong - Disasters, Blunders and Happy Accidents](https://www.unitconvertercalculator.com/blog/when-measurements-go-wrong) - [The Surprising Stories Behind Everyday Units of Measurement](https://www.unitconvertercalculator.com/blog/stories-behind-measurement-units) - [Metric vs. Imperial - The Complete Guide to the World's Two Measurement Systems](https://www.unitconvertercalculator.com/blog/metric-vs-imperial-complete-guide) - [Understanding Weight Units - Kilograms, Pounds, Stones & Ounces](https://www.unitconvertercalculator.com/blog/understanding-weight-units) - [Complete Baking Measurement Guide - Cups, Grams, Ounces](https://www.unitconvertercalculator.com/blog/baking-measurement-guide) ## See Also - [Carats to Stones](https://www.unitconvertercalculator.com/weight/carats-to-stones/)
