Table of Contents

    Welcome back, Brighterly family! As always, we’re thrilled to guide you on your thrilling adventure through the universe of mathematics. On today’s exploration, we’re going to unravel the mysteries of an everyday concept that connects us all, yet remains largely unnoticed – Measurement of Length.

    From the tallest buildings to the smallest ants, the planets in our solar system to the thickness of your math book, everything around us has a measurable length. It’s this hidden concept that helps engineers design spectacular structures, athletes break records, and astronomers traverse the cosmos. So let’s leap into the world of length measurement together and see the magic that lies in plain sight!

    What Is Length?

    Let’s start our journey into the world of measurement by asking ourselves – what is length? In the simplest terms, length is the distance from one end of an object to the other. But, as is often the case in mathematics, there’s a whole world of wonder behind this seemingly simple concept. Length isn’t just a measure of how long something is, it’s a fundamental principle that shapes our understanding of the world.

    Whether you’re a budding architect gauging the height of your future skyscrapers, an aspiring athlete tracking the distance of your sprint, or a future astronaut calculating the miles to Mars, length is at the heart of it all. It’s the unspoken language of the universe, helping us make sense of everything from the microscopic to the cosmic scale.

    How to Measure Length?

    Now that we know what length is, let’s understand how to measure length. At its core, measuring length is all about comparison. Imagine you’re in a race with your friends. How would you figure out who ran the fastest? By measuring the distance each of you travelled! Whether we’re baking our favourite cookies and need to measure ingredients, or we’re a carpenter building a house, we’re constantly measuring length, often without even realizing it!

    But remember, the process of measurement is a bit like telling a story – the unit of measurement we choose can change the narrative. For example, expressing the distance to the next town in inches wouldn’t be very practical, would it? This is why understanding different units of measurement is so crucial.

    Units to Measure Length

    When it comes to measurement, the world speaks in two primary languages – the metric and imperial systems. But before these systems came into play, people relied on non-standard units for their measuring needs.

    Non-standard units of measuring length


    The handspan is one of the oldest units of length known to humanity. It’s the distance from the tip of your thumb to the tip of your little finger when you stretch your hand out wide. While everyone’s handspan is unique, it was a handy unit of measurement during ancient times when standard units didn’t exist.


    Just like the handspan, the foot-span was another go-to unit of length. It was typically equal to the length of a person’s foot. But with the size of everyone’s foot being different, we needed a more uniform system. Enter, the standard units.

    Standard units of measuring length

    Metric System

    The metric system is the superhero of the measurement world. Its superpower? It’s universal. The metric system uses units like the meter, centimeter, and kilometer, which are used and understood worldwide. This makes it incredibly practical for everything from scientific research to international travel.

    Imperial System

    The imperial system is the other main player in the measurement game. This system, which uses units like the foot, inch, and mile, is primarily used in the United States. Even though it’s not as widely used as the metric system, understanding it is essential for a well-rounded grasp of measurement.

    Metric to Imperial System

    Sometimes, we need to translate between these two measurement languages. Converting from the metric to the imperial system is just like translating words from one language to another. For instance, if you want to know how many inches make a centimeter, the answer is approximately 0.39 inches.

    Imperial to Metric System

    The same goes for conversions from the imperial to the metric system. For example, if you have a measurement in feet and need to know its equivalent in meters, you can use a conversion factor. 1 foot translates to about 0.3048 meters.

    S.I. Unit of Length

    In the world of science, we have a universal measurement language known as the International System of Units, or S.I. The S.I. unit of length is the meter, defined as the distance that light travels in a vacuum in 1/299,792,458 of a second. This definition ensures that regardless of where you are in the universe, a meter remains a meter.

    Tools used for Measurement of Length

    In our measurement toolkit, we have various tools suited to different tasks. These include:

    1. Rulers: These are typically used to measure lengths under one foot or 30 centimeters. They’re perfect for small tasks like measuring the length of your notebook.
    2. Tape Measures: These flexible tools can measure longer lengths, making them ideal for larger projects like measuring the size of a room.
    3. Meter Sticks: These are essentially long rulers, typically used in science labs for various experiments.
    4. Odometers: These devices, often found in vehicles, measure the distance traveled. They’re how we know how far we’ve driven!
