30centimeter

30centimeter denotes a length of 30 centimeters, a unit in the metric system. A centimeter is one hundredth of a meter, so 30 centimeters equals 0.3 meters.

Equivalent measures include 300 millimeters and about 11.81 inches (using 1 inch = 2.54 centimeters).

Usage and context: This length is commonly used to describe the dimensions of objects, spaces, or components in fields where metric units are standard, such as engineering, design, packaging, and consumer products. It provides a convenient scale for mid-sized objects and aligns with common ruler markings and manufacturing tolerances.

Practical examples: The width of some laptops and display devices is around 30 cm. A standard dinner plate is often close to 30 cm in diameter. In textiles and construction, 30 cm is a convenient unit for planning and communication, though precise measurements may be given with more or fewer centimeters depending on the requirement.

Conventions: In formal writing, the unit is written as “30 centimeters” with a space. The concatenated form “30centimeter” is not standard in formal contexts but may appear in brand names, programming identifiers, or shorthand in informal use.
