Imperial Unit System

When it comes to precision measurement tools and devices such as mechanical micrometer, caliper, indicator, etc, we take the reading in inch reading. You need to know the inch reading is actually an imperial unit system. Here we are going to briefly discuss imperial unit system including its history, the units, and countries that keep … Read more

What is the Least Count of Micrometer?

Micrometer’s least count means the smallest increment figure that the micrometer’s scale provides. It’s also the smallest thickness or length that can be measured. For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, these row of numbers has 1 increment figure. Another example, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, … Read more

Micrometer Working Principle

In short, the idea behind how micrometers work is a combination of these two: the working principle of the differential screw and the distance magnifying that is affected by the thimble diameter. In this page, we only explain the micrometer working principle of the mechanic type one. Differential Screw According to Wikipedia, “A differential screw … Read more

How to Zero A Micrometer

Zeroing in micrometer is the process of adjusting the index line to line up straightly mark “0” of the thimble scale when the measuring faces of the micrometer are closed properly. In basic terms, it’s a way in order for the measuring tool to get repaired its zero error. How to zero a micrometer is … Read more

Ultimate Guide How to Use Tape Measures

Using a tape measure is basically easy. Things that you need to consider are the hook and the tape. On this page, we are going to discuss how to use the hook and read the tape. If you know how to use it and read the marks properly, that’s good, whereas if you are still … Read more

Laser Measure Working Principle

When talking about how laser measure works, the first thing that you have to learn is the laser itself. This is the physics artificial phenomenon that takes a big chunk of the portion on how the laser measure works. Other aspects to know are some basic math and light speed coefficient. As the laser measures … Read more

A Quick History of Micrometer

The word micrometer itself is a combination of two Greek words. These words are “micros and “metron”, the meaning of micros is small and the meaning of metron is measure, both of them combine to give micrometer its name. William Gascoigne was an astronomer who first invented a micrometric screw while measuring the star in … Read more

6 Tips Taking Care of A Tape Measure

One of the reasons why you should choose tape measures as your length measuring tool is their easy-to-maintain advantage while it provides great functions that you can’t obtain from an ordinary length measuring tool. Even though easy, if you don’t take care of it properly, it will break apart early. Here are some simple tips … Read more

How A Tape Measure Works: Why It Is Retractable?

A tape measure is actually a long ruler that can be bent and rolled-up so that we can get it housed in a case then pick it anywhere. It is a problem solver when we need a portable long-range ruler. That’s why carpenters, builders, etc are those who always pick tape measures for their measurement needs. … Read more

Calibration Vs. Verification Vs. Validation

Calibration is to find out the measurement error. According to the measurement error that is observed, verification is to decide whether it is within the tolerance (permissible error) or not. Then, validation is to make sure it measures what it’s meant to. In some cases, verification and validation overlap. Calibration According to NIST, calibration is … Read more
