When it comes to understanding the size of an object, length is a key measurement. In the International System of Quantities, length is a quantifiable distance. By determining the object's length, it is possible to determine its other dimensions, such as its width and height, or other measurements such as the circumference of a circular object. Length is the greatest of the two or three dimensions of a geometric shape or object. For example, the length and width of a rectangle can be used to accurately understand its size.
Measuring an object's length is an essential activity for many people. With the use of reliable measuring instruments, such as a ruler, measuring tape, and foot scale, determining the length of any item is a simple task. For instance, a ruler can be used to accurately determine the length of a pencil in inches, while a foot scale can be employed to assess the height of each student in the classroom. All of these measuring instruments provide precise measurements that give accurate results.
Units of Measuring Length
Measuring length is an essential part of everyday life, whether it’s for construction, cooking, or travel. Units of length come in two categories: standard and non-standard. Standard units are always the same and are universally accepted, such as metres, centimetres, inches, and feet. Non-standard units, on the other hand, may vary between people or things, such as a handspan or foot span.
The standard units of measuring length are widely known and used by everyone. Common examples of standard units include metres, centimetres, inches, feet, and yards, all of which can be accurately measured and compared. Non-standard units, however, lack such precision. Examples of these are finger breadth, a thread or rope, cubit, and pace. Since these units are based on subjective measurements, variations can occur from one person to the next, or from one thing to the next. For example, a toddler’s handspan is usually much shorter than an adult’s, and this can lead to different measurements of the same object.
Accurately measuring length is an important task, and understanding the various standard and non-standard units of length gives us the ability to do so confidently.
Length Unit Conversions
The metric system is an incredibly useful tool for measuring length, area, or distance. It uses a set of common terminology - kilometres (km), metres (m), decimeters (dm), centimetres (cm), and millimetres (mm) - to measure length and distance, making it much easier to calculate unit conversions.
If you want to be precise and accurate in your measurements, then using a length converter is the best way to go. Our online Length Converter Tool makes it simple to convert one unit of length into another. We have a comprehensive list of units supported, and you can find both imperial and metric conversions easily.
So if you need to convert from kilometres to metres, metres to centimetres, or from centimetres to millimetres, then using our online Length Converter Tool should be your first port of call. With accurate, reliable, and professional measurements, you can ensure you have the precise length for every project.
- Inch and
- light year
The inch, abbreviated as in or “, is a unit of length used in the Imperial and US Customary systems of measurement. Derived, by certain definitions, from the width of an average human thumb, the exact definition of an inch varies depending upon the language. In some languages, such as Norwegian, Afrikaans, Italian or French, the word for inch is derived from the word for thumb itself, or is simply the same word. In the 14th century, the inch was defined by the King of England as the length of three grains of barley - dry and round - placed end-to-end. Over the years, the definition of an inch has varied widely; however, since the 1950s, an internationally-accepted standard of precisely 2.54 centimeters to an inch has been in use. In other words, 1 in = 2.54 cm.
The foot (abbreviated as ft or ') is a unit of length in the Imperial / US customary system of measurement that is based on the human body. Standardized in the 1950s, a foot is now equal to 0.3048 meters exactly, which is 304.8 mm: 1 ft = 0.3048 m = 304.8 mm. This unit has been used since ancient times by various civilizations, though the length varied from one to the other. In Ancient Rome, a foot was considered equal to 11.6 inches (295.7 mm). Though this was the common standard, certain provinces used a length of 13.2 inches (334 mm) for the foot. In Ancient Greece, feet were anywhere between 10.6 to 13.8 inches (270 to 350 mm). During the Bronze Age in the Indus cities, a foot was equal to 13.2 inches (333.5 mm), while in Egypt, it was 12 inches (304.8 mm). Throughout its thousands of years of history, the foot has proven to be a reliable and precise measurement, and it continues to be used today in the US and other countries.
The meter, also known as metre in British English, is the foundation of measurement in many metric systems, including the International System of Units (SI). Historically, it has seen important developments as scientific methods of measurement have advanced. Now, the exact length of a meter is defined as being the distance traveled by light in a vacuum in one 299,792,458th of a second. This provides precision, accuracy and a professional level of excellence in terms of metrics-based measurement.
Metric measurement system
The Metric System, also known as the International System of Units (SI), is an international decimal system of weights and measures that is used globally. With the exception of just three countries, the Metric System is convenient, logical, and easy to use. Comprised of four fundamental base units - meter (m) for length, kilogram (kg) for mass, second (s) for time, and ampere (A) for electromagnetism - the Metric System is the standard for scientific and engineering calculations. With its efficient and highly accurate measurements, standardization of units provides a common language used by professionals the world-over.
