Centimeter (cm): The centimeter is equal to one one-hundredth of a meter (0.01 meters). It is commonly used for measuring shorter lengths, such as the height of a person or the dimensions of objects.
A "nail" is a traditional unit of length used for measuring cloth or fabric, particularly in some regions of India. The nail is based on the width of a finger, and it is typically equal to approximately 2.25 inches or about 5.715 centimeters.
Nails were historically used in the textile and clothing industry to measure the width of cloth or fabric. However, like many other traditional units of measurement for textiles, the nail has largely been replaced by more standardized and metric units, such as inches, centimeters, or meters, in modern times.
