In aluminum and glass work, the most important and fundamental thing is a perfect measurement. Whenever a new boy comes to the workshop to learn the trade, he faces the most difficulty in measuring because he lacks a technical understanding of the measuring tape. If you do not know how to read a measuring tape, you can never do cutting of the correct size, and a difference of even a single sootar can ruin the entire job. In today's detailed post, we will learn the measuring tape completely from start to finish, including what feet, inches, sootar, and millimeters are, and how they calculate against one another.
1. Calculation of Feet and Inches
When you open a measuring tape, large numbers are written along the top side; these represent inches, such as 1, 2, 3, 4, etc.
- How many inches are in a foot? There are exactly 12 inches inside one foot. When the number 12 appears on the tape, 1 foot is completed there. Similarly, 24 inches make 2 feet, and 36 inches make 3 feet.
2. Technical Calculation Inside an Inch (Sootar and Millimeters)
For excellent cutting, you must understand the fine lines present inside a single inch.

How many sootar are in an inch? In aluminum work, the term "sootar" is spoken the most. There are a total of 8 sootar inside one inch. The long lines between an inch on a measuring tape indicate the sootar:
- 2 sootar is called a quarter of an inch (1/4).
- At 4 sootar, half an inch (1/2) is completed.
- 6 sootar is called three-quarters of an inch (3/4).
- 8 sootar combine to make a full 1 inch.
- How many millimeters (mm) are in an inch? If you are taking measurements for glass, millimeters are the most important there. There are 25.4 millimeters inside one inch. Craftsmen also count it as 25 millimeters for general calculation.
3. Relationship Between Feet and Millimeters
The fitting of modern materials and imported frames is now done in millimeters, so knowing this calculation is mandatory:
- How many millimeters will be in a foot? Since there are 12 inches in a foot and 25.4 millimeters in an inch, if we multiply them, there are a total of 304.8 millimeters inside one foot. In simple craftsmanship calculation, it is taken as 305 millimeters.
- What is a centimeter? The small numbers written on the lower side of the measuring tape are centimeters. There are 10 millimeters inside 1 centimeter.
4. Golden Rules for Reading a Measuring Tape
- Always measure the first inch carefully: There is a small metal clip attached to the start of the measuring tape that moves. It is not broken; rather, it is designed to be flexible so that internal and external measurements come out completely equal.
- Learn the method of writing: If a measurement is 3 feet, 5 inches, and 2 sootar, always write it clearly on a slip so that no mistake occurs at the time of cutting.
Practice using the measuring tape daily at the workshop, because the cleaner your hand is at measuring, the more elegance and neatness will reflect in your work.
