What is Gradian ?

A Gradian (also known as gon or grade) is a unit of angle measurement used in some fields like surveying, engineering, and cartography. It’s an alternative to degrees and radians for measuring angles, with a focus on dividing angles into even parts for easier calculation.

Understanding a Gradian

A gradian is defined by dividing a full circle into 400 equal parts. Each of these parts is one gradian. This means:

  • A full circle equals 400 gradians.
  • A right angle (which is one-quarter of a circle) is 100 gradians.
Key Facts About Gradians
  • Relation to Degrees and Radians:

    • 1 gradian is equal to 0.9 degrees.
    • 1 gradian is also approximately equal to 0.0157 radians.
    • Since a full circle is 360 degrees, and a full circle is 400 gradians, 1 degree equals 10/9 gradians (or approximately 1.111 gradians).
    • Similarly, 1 radian is about 63.66 gradians.
  • Common Gradian Values:

    • 0 grad: Starting point, like 0° or 0 radians.
    • 100 grad: Equivalent to 90° or π/2 radians (a right angle).
    • 200 grad: Equivalent to 180° or π radians (a straight angle).
    • 300 grad: Equivalent to 270° or 3π/2 radians.
    • 400 grad: Equivalent to 360° or 2π radians (a full circle).
Why Use Gradians?

Gradians are particularly useful in applications where angles are frequently divided into quarters or decimals. For example:

  • Surveying: When surveyors measure land or set out construction projects, using gradians allows for simpler calculations when dealing with right angles or dividing an area into equal parts.
  • Engineering: Gradians can simplify the calculations involving angles that are multiples of 10, which are common in engineering designs.
Visualizing Gradians

Imagine a circle divided into four equal parts:

  • In degrees, each part is 90°.
  • In gradians, each part is 100 grad. This division makes it straightforward to work with right angles, which are common in many practical applications.
Practical Example

If an engineer needs to design a road that turns exactly 45 degrees, they can quickly convert this to 50 gradians (since 45° is half of 90°, and half of 100 grad is 50 grad). This ease of division is one of the reasons gradians are sometimes preferred in technical fields.

Summary
  • A gradian is a unit of angle measurement where a full circle is divided into 400 equal parts.
  • 1 gradian equals 0.9 degrees or approximately 0.0157 radians.
  • Gradians are especially useful in fields like surveying and engineering, where angles often need to be divided into even parts.
  • 100 gradians make a right angle, and 400 gradians make a full circle.

Understanding gradians can be beneficial in certain technical fields where simplicity and ease of calculation are important, especially when working with angles that are frequently divided into equal parts.




What is Revolution ?

A Revolution is a unit of angle measurement that describes a complete turn or rotation around a central point. It’s used to measure how much something has rotated or turned in a full circle.

Understanding a Revolution

Imagine you’re standing in the middle of a circle and you start turning. If you turn all the way around and end up facing the same direction you started from, you’ve completed one revolution. This is the same as making a full 360-degree turn.

Key Facts About Revolutions
  • Full Circle:

    • 1 revolution equals one full turn, which is the same as 360 degrees (360°).
    • 1 revolution also equals 2π radians (since a full circle in radians is 2π).
    • 1 revolution equals 400 gradians (because a full circle is 400 gradians).
  • Fractional Revolutions:

    • Half a revolution is a half-circle or a turn of 180 degrees.
    • Quarter of a revolution is a quarter-circle or a turn of 90 degrees.
  • Common Uses:

    • Rotational Motion: Revolutions are commonly used to describe the number of times an object rotates, such as wheels, gears, or planets.
    • Engineering and Physics: In mechanics, revolutions per minute (RPM) is a standard way to measure the rotational speed of engines and machinery.
    • Cycling and Sports: The number of times a cyclist’s pedals complete a full turn can be counted in revolutions.
Visualizing Revolutions

Picture a clock’s second hand moving around the face of the clock:

  • As it moves from the 12 all the way around back to the 12, it completes 1 revolution.
  • If it only goes from the 12 to the 6, it completes half a revolution.
Practical Example

If you spin a toy top, each full spin it makes is one revolution. If the top spins quickly, it might make several revolutions in just a few seconds. If you’re calculating how fast it’s spinning, you might say it’s making a certain number of revolutions per minute (RPM).

Summary
  • A revolution is a unit of angle measurement that represents a full 360-degree turn.
  • 1 revolution equals 360 degrees, 2π radians, or 400 gradians.
  • Revolutions are used to describe complete rotations in various fields, including engineering, physics, and everyday activities.

Understanding revolutions is essential when dealing with rotating objects or systems, making it a key concept in both everyday life and technical fields.
