Measuring length is a fundamental concept that has been in use for centuries. Everyone needs to measure objects and distances at some point in their life. From construction workers to students, measuring objects with accuracy is of utmost importance in their field. But what do you use to measure length? In this article, we’ll explore the various measuring tools used for measuring length.
The Measuring Tape
Measuring tape is a versatile tool that is widely used for measuring length. It is flexible and can measure objects of various shapes and sizes. Measuring tapes come in different lengths, but the most common length is 25 feet.
- Measuring tapes can be made of fabric or metal.
- They are easy to use and can be operated by a single person.
- Measuring tapes are durable and can last for years if maintained correctly.
How to Use a Measuring Tape?
Using a measuring tape is simple. Follow these steps:
- Hold the starting end of the tape on the object’s beginning point.
- The tape can be extended to the desired point and kept in place.
- After reading the measurement, you can retract the tape and store it.
Rulers and Yardsticks
Rulers are flat, thin measuring sticks used to measure objects with a flat surface. They come in different lengths, but the most common length is 12 inches. Yardsticks, on the other hand, are longer than rulers and measure 36 inches.
- Rulers and yardsticks are generally made of wood, metal, or plastic.
- They are less flexible than a measuring tape.
- Rulers and yardsticks are more accurate than tapes but harder to use.
How to Use a Ruler or Yardstick?
Using a ruler or yardstick is relatively easy. Follow these steps:
- Place the starting end of the ruler on the object’s starting point.
- Align the ruler with the object, making sure it’s straight.
- Read the measurement at the end of the object.
Vernier caliper is an instrument used to measure length, thickness, and diameter accurately. They are generally used by engineers and scientists, where precision is of utmost importance.
- Vernier calipers come in two types: Digital and Analog.
- They are accurate to a fraction of a millimeter.
- Vernier calipers have a measuring range of up to 200mm.
How to Use Vernier Calipers?
Using Vernier calipers can be a bit tricky, but once you get the hang of it, you will get more accurate measurements. Follow these steps:
- Place the object between the jaws of the caliper.
- Close the jaws gently using the thumbwheel.
- Read the measurement from the scale when the jaws are closed.
Micrometer, also known as a screw gauge, is an instrument used to take measurements with higher precision than a ruler or measuring tape. They are typically used in mechanical engineering, manufacturing, and other related fields.
- Micrometers come in two types: Vernier and Digital.
- They have a measuring range of up to 25mm.
- Micrometers are accurate to a hundredth of a millimeter.
How to Use a Micrometer?
Using a micrometer requires practice, but following these steps can help:
- Close the jaws of the micrometer using the ratchet.
- Place the object between the jaws and tighten it gently.
- Read the measurement from the micrometer’s scale when the jaws are closed.
Laser Distance Meters
Laser distance meters are digital measuring tools used to measure the distance between two objects. They are typically used in construction, manufacturing, and engineering to measure distances accurately.
- Laser distance meters are small and easy to use.
- They are accurate to within a few millimeters.
- Laser distance meters work by emitting a laser beam onto the target, which calculates the distance based on the time taken for the beam to reflect back to the meter.
How to Use a Laser Distance Meter?
Using a laser distance meter is easy. Follow these steps:
- Hold the laser distance meter at the object that needs to be measured.
- Press the button on the meter and aim the laser beam on the endpoint.
- The laser distance meter will display the exact measurement on the screen.
There are different measuring tools used to measure length, depending on the accuracy and precision required. Most measuring tools, such as rulers and measuring tapes, don’t require special skills to use, while some require practice, like micrometers and Vernier calipers. It’s essential to choose the right measuring tool for the job, as accuracy is crucial in most fields of work.
