Ell
An ell is a historical unit of length that was commonly used in medieval Europe, especially for measuring textiles and cloth. Its length varied by region but was typically about 45 inches (approximately 1.143 meters).
The ell originated from the length of the arm or forearm and was often used by tailors and merchants to measure fabric. Different countries had their own versions—for example, the English ell was about 45 inches, while the Scottish ell was longer, around 37 inches.
Although obsolete today, the ell played an important role in trade and clothing production before standardized measurements became widespread.

Decimeter
A decimeter (dm) is a unit of length in the metric system. It is equal to one-tenth of a meter, or 10 centimeters (1 dm = 0.1 m = 10 cm). While not as commonly used as centimeters or meters in everyday life, decimeters are still important in scientific and technical measurements. For example, a small book or a tablet might be about 2 to 3 decimeters long. The symbol for decimeter is "dm". Although it sits between the centimeter and meter in size, people often skip using decimeters and go directly from centimeters to meters. Still, it's a helpful unit when you need a mid-sized measurement.
