The new technology advancements these days have got us expecting nothing less than pinpoint accuracy in measurements. Be it distance measurement through GPS or Heart Rate on the Smartwatch, measurement tools have become better than ever. You can put the advancement into perspective by looking at the measurement tools used in ancient times. 

People used thumbs for an inch, a foot’s length for afoot, and the yard was the distance between King Henry’s nose to his arm. Ke As the standard units of measurements of various quantities have been defined over the years, tools have been made and upgraded. Measurement tools have become an indispensable asset of our daily life. 

Even a kid would need necessary tools like a ruler, thermometer, measuring tape, etc. If you take up DIY projects or like to do repair work in your house, you’d need many measuring tools handy. Here are some important types of measuring tools that you should know about.

Types of Measuring Tools

1. Ruler

It is easily a universal measuring tool. From a kindergarten student learning how to make shapes, to working on those school projects in the college, the ruler comes useful everywhere. It’s so simple to use and has such vast uses that you may want to ignore this point!

But that has been made possible because of William Bedwell, who designed the world’s first ruler in the 16th century. The fundamental purpose of a ruler is to draw straight lines and to measure the length and height of a geometrical shape. You can find different types of rulers based on different purposes.

School students use a standard 15cm ruler for drawing lines and shapes in their notebook. Engineering drawing students, designers, and other such industry professionals use a large ruler measuring 30cm or more. You can find rulers made of plastic, wood, and metal in the market. Of course, plastic is the cheapest of them all.

A measuring tape is a carpenter’s best friend. If you like to save some bucks and build handy furniture and stuff on your own, a measuring tape would be an indispensable asset for you. The essential purpose of a measuring tape is to measure the length of an object. It is essentially a metal or nylon tape folded into a coil shape in a plastic enclosure.

Just like a ruler, the tape has three types of markings on it- inch, centimeter, and millimeter. It is effortless to use this instrument. You just have to hold the open end of the tape and pull it to the size of the object. Once you have taken the measurement, only release the tape, and it gets retracted back into the roll

Measuring tapes have quite a few benefits over regular rulers. They are portable, can be kept in the pocket, and can measure long objects. You can find these tapes in multiple sizes between 12 inches to 35 inches. It fits in the palm well, and many companies also offer a switch to lock the tape in place.
