The term "length" refers to the size of an object or the distance between two points. The length of an object or the distance between two places is measured in length. It is used to determine the size of an object or the distance between two points.
In order to figure out what the basic length units are, we discover that there isn't one. This is because many measurement methods or systems are currently in use all over the world. However, the most commonly used length units today are US customary units and metric units, which include both SI and non-SI units. In addition, some countries continue to utilise British Imperial units. In this blog post, we'll be running through just a few of the most common units of measurement!
Units of Measurement List
There are two types of units of measurement:
Non Standard unit is one unit from units of measurement list. Children in Foundation Stage learn about measuring without needing to read any scales by using non-standard units.
The objective of non-standard measures is to focus the child on the concept of heavier, lighter, longer, shorter, etc. before they proceed onto the next step of measuring using standard units. Reading scales of any kind is a difficult ability in and of itself.
For example, in order to measure height, handspan or foot is used but all people don’t have equal length of hand or foot this implies getting a standard unit of measurement.
A common unit of measurement is a quantifiable language that makes the relationship between the item and the measurement clear to all parties.
In the US, it is measured in inches, feet, and pounds; in the metric system, it is measured in centimetres, metres, and kilograms.
For example, a ruler (used to measure height), measuring tape (used to measure length), scale (used for weight measurement), thermometer (temperature measurement), etc all are used to measure different types of things.
Non-standard Unit and Standard Unit
SI Unit of Length
The SI unit of length in the metric system is the metre.
The following are some of the other length units:
Tools for Measuring Length
Tools help to get accurate measurements and this is the same for everyone at any place. A few tools that use for measuring length are:
Order of Measurement
Small lengths (i.e. distances) are measured in cm and mm, while long lengths (i.e. distances) are measured in m and km. The 'Metre,' abbreviated as 'm,' is the standard unit of length.
One metre of length is divided into 100 equal parts. Each division is called a centimetre and is denoted by the letter 'cm.' As a result, 1 metre equals 100 centimetres.
The kilometre is the unit of measurement for the longest distance. One kilometre is divided into 1000 equal parts. A metre is the unit of measurement for each division. As a result; 1 kilometre equals 1000 metres.
Order of Measurement
Units of length and their counterparts, according to the length conversion charts, are:
1000 m = 1 kilometre (km) = 10 Hectometres (hm)
10 Decametres (dcm) = 100 Metres = 1 Hectometre (hm)
1 Metre (m) = 10 Decimetres (dm) = 100 Centimetres (cm) = 1000 Millimetres (mm)
10 Centimetres = 1 Decimetre (dm) (cm)
1 decimetre = 0.1 Metre
1 Centimetre (cm) = 10 Millimetres (mm) = 0.01 Metre
1 Millimetre = 0.001 Metre
Units of Length
A metric system is a unit of measurement for distance, length, volume, weight, and temperature. There are many different types of metric systems. It is built on three fundamental units that can be used to measure practically anything in the world.
Kg- kilogram, used to measure the mass
S- second, used to measure time
M- metre, used to measure the length
L-litre used to measure the length
Basic SI unit
Types of Metric Systems
There are many different types of metric systems mentioned below;
1. SI System
The SI Units (Standard International System of Units) define the metre, kilogram, and second correctly.
2. CGS System
The CGS system of units is another system of expressing units in terms of length, weight, distance, and time.
3. Metric Units Smallest to Largest
Order of metric units smallest to largest: Nanometer, Millimetre, Decimeter, Metre, Decameter, Hectometer, Kilometre
Length measurement is used to determine an object's length or the separation between two locations. It is employed to calculate an object's size or the separation between two spots. US customary units and metric units, which comprise both SI and non-SI units, are currently the most widely used length units. Additionally, some nations still make use of British Imperial units. The yard is the basic unit of length in both the Imperial and United States customary systems. In 1799, the metric system was created. The metric system of units is consistent and logical. This is a big benefit for usage in the home, in education, in business, and in science.
