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.
Ell
An ell is an Imperial unit of length equal to 45 inches (1.143 m), historically used as the standard measure of cloth in English commerce.
The ell derives from old English elna (forearm) and was standardised in medieval English trade as the cloth-measuring yard equivalent. The English ell is 45 inches; other regional ells differed.
Ells appear in historical English commerce records (especially cloth and tapestry trade). Used in legal documents through the 19th century; rare in modern commerce but referenced in literary and historical contexts.
Medieval English cloth-trade origin; standardised at 45 inches; became exact via the 1959 International Yard and Pound Agreement.

Worked examples
Example 1 — Convert 1 cm to ell:
1 × 0.0087489064 = 0.0087489064 ell
Example 2 — Convert 100 cm to ell:
100 × 0.0087489064 = 0.8748906387 ell
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 ells — converting between these adjacent units is one of the most-used length conversions globally.
180 cm × 0.0087489064 = 1.5748031496 ell
Real-world example — Furniture and large objects
A 72-centimeter piece of furniture converts to a value in ells 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 × 0.0087489064 = 0.6299212598 ell
Real-world example — Children's height milestones
A 150-centimeter-tall child measures a value in ells that's commonly used for theme-park ride height requirements when travelling between countries that use different measurement units.
150 cm × 0.0087489064 = 1.312335958 ell
