Units explained
Centimeter
A centimeter is a metric unit of length equal to one hundredth of a meter (1/100 m). It is one of the most commonly used SI sub-units in daily life, especially for measuring small objects, body dimensions, paper sizes, and short distances.
The centimeter emerged from the French metric system established by the French Academy of Sciences in 1793. The metric system introduced decimal-based prefixes (milli-, centi-, deci-, deca-, hecto-, kilo-) to create proportional sub-units of the meter.
Centimeters are the standard unit for everyday measurement in nearly every country outside the United States. They are used for body height, clothing sizes, rainfall, paper formats (A4 is 21 × 29.7 cm), screen dimensions, and most consumer product specifications.
Developed in France during the late 18th century as part of the metric system designed by the French Academy of Sciences. Formally adopted in France in 1795 and ratified internationally through the Metre Convention signed in Paris in 1875.
Cubit
The UK cubit is an Imperial unit of length equal to 18 inches (457.2 mm). It represents the historical distance from the elbow to the tip of the middle finger.
Cubits derive from ancient body-measure traditions found in Mesopotamia, Egypt, and the eastern Mediterranean. The English customary cubit was standardised at 18 inches in medieval times.
UK cubits are rare in modern commerce but appear in historical English texts, biblical references, and historical reconstructions. Different cultures used cubits of different lengths.
Ancient origin; standardised at 18 inches in English customary practice; became exact via the 1959 International Yard and Pound Agreement.

- The product is the equivalent value in cubits (cubit).
- To reverse, multiply the cubit value by 45.72.
Worked examples
Example 1 — Convert 1 cm to cubit:
1 × 0.021872266 = 0.021872266 cubit
Example 2 — Convert 100 cm to cubit:
100 × 0.021872266 = 2.1872265967 cubit
Real-world example — Children's height milestones
A 150-centimeter-tall child measures a value in cubits that's commonly used for theme-park ride height requirements when travelling between countries that use different measurement units.
150 cm × 0.021872266 = 3.280839895 cubit
Real-world example — Body height conversion
You enter your height as 180 centimeters into an international job or visa application. The form then asks for the same value in cubits — converting between these adjacent units is one of the most-used length conversions globally.
180 cm × 0.021872266 = 3.937007874 cubit
Real-world example — Furniture and large objects
A 72-centimeter piece of furniture converts to a value in cubits that's easier to mentally compare with room dimensions. This is the typical workflow when shopping internationally and product specs use a different unit than your room measurements.
72 cm × 0.021872266 = 1.5748031496 cubit
