What System of Measurement Is Commonly Used in Carpentry
The system of measurement commonly used in carpentry in the United States is the Standard American English (SAE) system, which includes feet and inches.
The SAE units allow materials to be bought and cut down to fractions of an inch, providing a high level of precision needed in carpentry.
However, with the use of digital design and drafting technologies, the need to convert fractions to decimals for greater accuracy arises.
To address this, the Engineer’s Scale, also known as decimal feet, is used in carpentry.
It allows for measurements to be taken in feet while adding the precision of decimals.
Did You Know?
1. The system of measurement commonly used in carpentry is known as the Imperial System, where units are based on inches, feet, yards, and pounds.
2. The inch, a fundamental unit of the Imperial System, is defined as the length of three barleycorns placed end to end. This measurement dates back to the reign of King Edward II of England.
3. The term “stud” in carpentry refers to vertical wooden beams used to frame walls. The standardized length of a stud in the United States is 92 and 5/8 inches, which accounts for the typical width of a sheet of drywall.
4. The origin of the term “board foot” in carpentry refers to the volume occupied by a board measuring 1 foot by 1 foot by 1 inch or its nominal size equivalent. This measurement allows woodworkers to easily calculate the amount of lumber required for a project.
5. The term “pitch” in carpentry refers to the angling of a roof. It is expressed in terms of a ratio, such as 1:12, where the first number represents the vertical rise and the second number represents the horizontal run. For example, 1:12 indicates that for every 12 inches horizontally, the roof rises 1 inch.
The Continued Use Of Feet And Inches In The United States Carpentry Industry
Despite several attempts to convert to the metric system, the United States still predominantly uses feet and inches as its system of measurement in the carpentry industry. While many countries around the world have embraced the metric system for its simplicity and ease of conversion, the United States continues to adhere to its traditional system of measurements. This preference for the imperial system can be attributed to a variety of factors, including the legacy of historical measurement systems, the convenience of working with fractions, and the practicality of U.S. standard sheet sizes.
The United States, rooted in historical traditions, has a long-standing attachment to the imperial system. The early remnants of this system can be traced back to ancient civilizations, such as the Egyptians and Romans, who based their units of measurement on body parts like the foot and inch. In fact, the Romans even divided the foot into twelve subunits called unicae, which later informed the concept of twelve inches in the imperial system. Over time, the twelve-inch foot became the standard unit of measurement in England around the twelfth century and eventually found its way to the United States.
Carpentry, specifically, adopted the imperial system due to its compatibility with the practicalities of the field. The United States carpentry industry primarily operates using SAE units, where materials are purchased and cut down to fractions of an inch. While this may seem cumbersome at first, it allows for greater precision and ease of division in calculations. For example, the number 12, which the imperial system conveniently divides into 2, 3, 4, and 6, makes calculations involving thirds much simpler. This advantage of easy division is particularly valuable in carpentry, as precise measurements are essential for ensuring the structural integrity and aesthetic appeal of constructed objects.
With the advent of modern digital design and drafting technologies, the need for more accurate measurements became crucial. This led to the emergence of the Engineer’s Scale, also known as decimal feet, which combines the convenience of feet with the precision of decimals. The Engineer’s Scale allows professionals such as engineers, surveyors, architects, and builders to measure using feet while adding decimal precision. By converting measurements like 5 feet 6 inches to 5.5 feet and 3 feet and 1/8 inch to approximately 3.01 feet, the Engineer’s Scale enhances accuracy in carpentry projects. However, confusion may arise if someone mistakenly uses an Engineer’s Scale tape measure when they were expecting an SAE tape measure, as the measurements can differ. Fortunately, companies like Keson offer a wide range of tape measure options that cater to different unit preferences, including SAE, metric, and Engineer’s Scale, with dual units for easy conversions.
