What Is This Tool?

This tool converts weight measurements from stone (UK), an imperial unit commonly used in the UK and Ireland for body weight, into carats, the standard unit for gemstone and pearl mass. It facilitates translating larger mass values into very fine gemstone weight units.

How to Use This Tool?

  • Enter the weight value in stone (UK) units.
  • Select stone (UK) as the input unit and carat [car, ct] as the output unit.
  • Click convert to see the equivalent weight in carats.
  • Use the results to compare or record weights in gemstone scales.

Key Features

  • Converts stone (UK) units to carat [car, ct] precisely.
  • Easy-to-use, browser-based interface suitable for quick conversions.
  • Supports weight conversions relevant to jewelry, gemology, and traditional contexts.
  • Displays large numeric results reflecting small mass units in gemstones.

Examples

  • Convert 2 stone (UK): 2 × 31751.4659 = 63502.9318 carat.
  • Convert 0.5 stone (UK): 0.5 × 31751.4659 = 15875.73295 carat.

Common Use Cases

  • Translating body weight or agricultural weights measured in stone (UK) into carats for gemstone comparison.
  • Weighing and pricing diamonds and pearls in the jewelry industry.
  • Using gemological certificates to document gemstone weights.
  • Converting traditional market measures to units used in specialized manufacturing or quality control.

Tips & Best Practices

  • Remember that stone measures larger masses while carat is for very fine weights, so numeric values can become large.
  • Validate conversions by considering intermediate SI units like kilograms for increased accuracy if needed.
  • Use the converter for informal and regional measurements from the UK and Ireland relevant to body or agricultural weights.
  • Double-check units when applying conversions in professional gemological or manufacturing contexts.

Limitations

  • Stone is an informal and regional unit with limited use outside the UK and Ireland.
  • Conversions result in very large numbers due to the scale difference between stone and carat.
  • For higher precision, conversions typically require intermediary standard SI units such as kilograms.
  • Not suited for daily practical use outside specialized or traditional contexts because of unit scale disparity.

Frequently Asked Questions

What is a stone (UK) used for?
The stone (UK) is mainly used informally in the UK and Ireland to express human body weight and occasionally in sports and traditional agricultural contexts.

Why convert stone to carats?
Converting stone to carats allows comparison or translation of larger weights into the fine mass units used in jewelry, gemology, and pearl grading.

Is the stone an official unit internationally?
No, the stone is a non-SI, informal unit mostly regional to the UK and Ireland and not officially recognized in global standards.

Key Terminology

Stone (UK)
An imperial unit of mass equal to exactly 14 avoirdupois pounds or 6.35029318 kilograms, used informally mainly in the UK and Ireland for body weight.
Carat [car, ct]
A unit of mass primarily for gemstones and pearls, exactly 200 milligrams, subdivided into 100 points for precise measurement.
Conversion Rate
The factor used to compute an equivalent weight from stone (UK) to carat, specifically 1 stone (UK) equals 31751.4659 carats.
