A decimeter (dm) is a unit of length in the metric system equal to one-tenth of a meter (0.1 m).
Its plural form is decimeters.
One of the most important uses of the decimeter is in measuring volume.
A cubic decimeter (dm3) is the volume of a cube with edges that are one decimeter long. This connection is beneficial, as one cubic decimeter is precisely equal to one liter (L).
This direct relationship (1 dm3 = 1 L) makes the decimeter a fundamental unit in chemistry and physics for calculating liquid volumes and densities.
The decimeter serves as a convenient intermediate unit between the meter (m) and the centimeter (cm). It provides a practical step in the metric system's base-10 structure.
Here are the key conversions:
While less common in everyday conversation, the decimeter is often used in specific fields, such as woodworking and shoemaking, for measurements that are too large for centimeters but too small for fractions of a meter.
The name "decimeter" comes from the Latin word decimus, meaning "tenth."
The prefix "deci-" always signifies one-tenth (1/10 or 10-1) of a base unit.
Understanding this prefix makes it easy to convert between different metric units.
An inch (in) is a standard unit of length used in the imperial and United States customary systems.
It is most commonly known as 1/12 of a foot. The plural form is "inches."
For a quick inch definition, here are the most important conversions:
The history of the inch goes back centuries. The word "inch" itself originates from the Latin word uncia, meaning "one-twelfth," which highlights its relationship to the larger unit of a foot.
Early definitions were often based on natural reference points. For a long time, an inch was widely considered to be the width of a man's thumb at the base of the nail.
To create a more reliable standard, 14th-century English King Edward II officially defined the inch as the length of three grains of barley placed end to end.
While the inch is an imperial unit, its official modern definition is based on the metric system.
Since 1959, an international agreement has defined the inch as exactly 2.54 centimeters (or 25.4 millimeters).
This universal standard, agreed upon by the United States, the United Kingdom, and other nations, ensures that the inch has a precise and globally recognized value.
This consistency is crucial for international trade, engineering, and science.
In fields that require extreme accuracy, such as engineering and machining, the inch is often divided into even smaller parts.
One-thousandth of an inch (1/1000 or 0.001 inches) is commonly known as a "thou" or a "mil."
Although very small, this unit is crucial for defining tolerances in the manufacture of engine components, electronic devices, and other precision equipment, where minute differences can have significant effects.
By comparison, a standard piece of paper measures roughly 2–4 thou in thickness.
