Fixed at 14 pounds by British statute in 1835.

Metric / SI

Centigram

What is a centigram?

A centigram (cg) equals 0.00001 kilogram, or 0.01 gram.

Origin of the centigram

From the SI prefix 'centi-' (from Latin 'centum', hundred).

Where it is used

Used in pharmacology and analytical chemistry.

When and where it was developed

Part of the original metric system of 1795.

Stone (UK) to Centigram conversion formula

The relationship between stones (uk) and centigrams:

1 st = 635029.318 cg
1 cg = 1.57473e-6 st

To convert stones (uk) to centigrams, multiply the value in stones (uk) by 635029.318. To reverse, multiply centigrams by 1.57473e-6.

Type a value into the calculator. The result in centigrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Centigram to Stone (UK) converter for the reverse direction.

Step-by-step: convert stones (uk) to centigrams

  1. Write down the value in stones (uk) (st).
  2. Multiply that value by the factor 635029.318.
  3. The product is the equivalent value in centigrams (cg).
  4. To reverse, multiply the centigram value by 1.57473e-6.

Worked examples

Example 1 — Convert 1 st to cg:
1 × 635029.318 = 635029.318 cg

Example 2 — Convert 100 st to cg:
100 × 635029.318 = 6.350293e+7 cg

Real-world example — Sub-meter precision

A 0.001-stone (uk) (1 mm) tolerance equals 1,000 centigrams — useful for surface-finish specs, where macro-scale dimensions are given in the larger unit but feature roughness in the smaller.

0.001 st × 635029.318 = 635.029318 cg

Real-world example — Macro-to-micro scale comparison

2 stones (uk) of measurement converts to a very large number in centigrams — useful in materials science when comparing bulk-sample dimensions to feature-level surface specs.

2 st × 635029.318 = 1270058.6359999999 cg

Real-world example — Macroscopic to microscopic

One stone (uk) equals a million centigrams. Optical engineers calculating coherence length compare macro-scale path lengths with micro-scale wavelength differences using exactly this conversion.

1 st × 635029.318 = 635029.318 cg
