It’s approximately equal to the width of the tip of an adult’s thumb, making it a convenient and easily recognizable measurement. Interestingly, the inch has a rich historical background, dating back to the Roman Empire, where it was originally defined as the width of a man’s thumb. Over time, it has evolved into the standardized measurement we use today.
How to Measure 20 Inches?
Measuring a length of 20 inches accurately can be done using various methods and tools. Here are four common methods along with step-by-step instructions for each:
1. Using a Ruler or Tape Measure:
This is the most straightforward method and requires a ruler or tape measure with inch markings.
Instructions:
- a. Place one end of the ruler or tape measure at the starting point of the length you want to measure.
- b. Extend the ruler or tape measure along the object or surface you are measuring until you reach the 20-inch mark.
- c. Ensure that the ruler or tape measure is straight and not bent or curved.
- d. Read the measurement where the 20-inch mark aligns with the edge of the object or surface. This is your accurate 20-inch measurement.
2. Using a Combination Square:
A combination square is a versatile tool that can be used for both measuring and marking.
Instructions:
- a. Open the combination square to a 90-degree angle, ensuring that the ruler or measuring blade is securely locked in place.
- b. Place one end of the square at the starting point of the length you want to measure.
- c. Slide the combination square along the object or surface until the 20-inch mark aligns with the edge.
- d. Read the measurement where the 20-inch mark aligns with the edge of the object or surface.
3. Using a Carpenter’s Square:
A carpenter’s square, also known as a framing square, is another tool that can be used for measuring longer lengths accurately.
Instructions:
- a. Place one end of the carpenter’s square at the starting point of the length you want to measure.
- b. Align the long leg of the square with the edge of the object or surface.
- c. Slide the square along the object or surface until the 20-inch mark on the long leg aligns with the edge.
- d. Read the measurement where the 20-inch mark aligns with the edge.
4. Using a Digital Caliper:
A digital caliper is a precise measuring instrument commonly used in machining and engineering.
Instructions:
- a. Place the jaws of the digital caliper on either side of the object you want to measure.
- b. Ensure that the jaws are firmly against the object and not at an angle.
- c. Press the “zero” or “tare” button on the digital caliper to reset the measurement to zero.
- d. Carefully open the jaws of the caliper until they span the 20-inch length.
- e. Read the measurement displayed on the digital screen. This is your accurate 20-inch measurement.
Remember to handle the tools carefully and ensure they are properly calibrated for accurate measurements. If precision is crucial, consider using multiple measuring methods to verify the accuracy of your measurement.
