Correct Measurement Notation: 5′7″ vs. 5.7

When discussing height or any other measurement, it is crucial to use the correct notation. Many people find it confusing to differentiate between measurements such as '5 feet 7 inches' and '5.7 inches.' This article will clarify these concepts and provide guidance on the proper way to write and understand these measurements.

Understanding Feet and Inches

To start, it is essential to understand the relationship between feet and inches. Typically, feet are used in combination with inches to represent a length or height more precisely. Here’s the basic breakdown:

1 foot 12 inches Therefore, 5 feet 7 inches is equal to 67 inches (5 x 12 7 67) And 5.7 inches is a much shorter measurement, approximately equal to 14.478 centimeters

Proper Notation for Measurement

When writing a measurement, it is important to use the correct symbols. Feet are typically denoted by the apostrophe symbol ('), and inches are denoted by the double quotes (").

5′7″ vs. 5.7

Let's break down the differences:

5′7″: This represents 5 feet 7 inches. Here, the prime symbol (') denotes feet, and the double quotes (“) denote inches. Both 5′7” and 5 feet 7 inches are correct ways to write this measurement. 5.7 inches: This is a much shorter measurement, approximately 14.5 centimeters. It is not the same as 5′7″. 5′7 ft: This is incorrect because the 7 should be in inches, not feet.

It is also important to note that in the US Customary system, all measurements are defined based on the SI metric system, though they are used in a different form.

Language vs. Cultural Norms

Language often collides with cultural norms and personal preference when it comes to stating one's height. In many countries, height is commonly expressed as decimal feet, like 5.7 feet. However, in the United States, it is more common to use the traditional notation (feet ' and inches ”).

For example, in Portland, Oregon, where things tend to be more casual, you might hear people say '5.7 feet' or '5 feet 7 inches.' However, if you are writing in a formal context, it is best to use 5′7″.

Why Use 5′7″?

The preferred representation for 5 feet 7 inches is 5′7″. Here are a few reasons why:

Clarity**: Writing it as 5′7″ clearly indicates that we are referring to a height measurement. Consistency**: Using the double quotes (") for inches ensures consistency across all measurements. Bedrock of Custom Measurement**: While many measurements are derived from the metric system, the US still uses the traditional notation in daily usage.

It is also acceptable to use 5′7 without the inch symbol because it is understood to mean '5 foot 7 inches.' However, using 5.7 inches is incorrect as it is a much shorter measurement and does not represent 5 feet 7 inches.

Conclusion

Several factors come into play when expressing height measurements. Whether you are in a formal or casual setting, ensuring that you use the correct notation is crucial. Understanding the differences between 5′7″ and 5.7 inches will help you communicate accurately and avoid confusion.
