Understanding unit conversions is a fundamental skill, especially when dealing with measurements. This article simplifies the process of converting inches to feet, focusing specifically on converting 90 inches. We'll break down the conversion process step-by-step, providing practical examples and addressing common questions.
1. The Foundation: Inches and Feet
Before diving into the conversion, let's establish the basic relationship between inches and feet. The imperial system of measurement, commonly used in the United States, defines a foot as exactly 12 inches. This means that one foot is composed of twelve individual inches. This fundamental relationship is the key to all inch-to-foot conversions.
2. Converting 90 Inches to Feet: The Calculation
To convert 90 inches to feet, we simply divide the total number of inches by the number of inches in a foot (12). The calculation is as follows:
90 inches / 12 inches/foot = 7.5 feet
Therefore, 90 inches is equal to 7.5 feet.
3. Understanding the Result: Feet and Inches
The result, 7.5 feet, means we have 7 full feet and an additional half-foot. Since half a foot is equal to 6 inches (half of 12 inches), we can also express 90 inches as 7 feet and 6 inches. This dual representation is useful in various contexts. For example, when measuring lumber, you might see it listed as 7'6", where the ' represents feet and the " represents inches.
4. Practical Examples: Real-World Applications
Let's look at some practical examples to illustrate the usefulness of this conversion:
Building a fence: If you need to buy fence posts spaced 90 inches apart, you can easily determine that you'll need posts spaced 7.5 feet apart.
Sewing a quilt: If a quilt pattern requires fabric strips measuring 90 inches long, you would need strips that are 7 feet and 6 inches long.
Planning a room: If you are planning a room with a wall length of 90 inches, you can easily represent this as 7.5 feet on your floor plan.
Measuring a piece of furniture: Determining the length of a sofa might be easier to grasp in feet than in inches. A 90-inch sofa is clearly a 7.5-foot long sofa.
These examples demonstrate how understanding the conversion between inches and feet simplifies various tasks and improves clarity in measurement.
5. Beyond 90 Inches: Applying the Method to Other Conversions
The method used to convert 90 inches to feet can be applied to any inch-to-foot conversion. Simply divide the total number of inches by 12 to get the equivalent number of feet. If the result is a decimal, the whole number represents the number of full feet, and the decimal portion can be multiplied by 12 to find the remaining inches.
Key Takeaways
There are 12 inches in 1 foot.
To convert inches to feet, divide the number of inches by 12.
The result can be expressed as a decimal representing feet or as whole feet and remaining inches.
Understanding this conversion is crucial for various practical applications involving measurements.
