165 cm to Feet and Inches: A Beginner's Guide to Metric-Imperial Conversion
Understanding different units of measurement can be tricky, especially when dealing with conversions between systems like the metric (centimeters, meters, etc.) and the imperial (inches, feet, yards, etc.) systems. This article will guide you through converting 165 centimeters (cm) to feet and inches, breaking down the process step-by-step in a way that's easy to understand, even if you're new to unit conversions.
Imagine you're buying a curtain rod online. The website lists the rod length as 165 cm, but your window measurements are in feet and inches. To ensure a perfect fit, you need to convert 165 cm to the familiar feet and inches system. Let's learn how!
Section 1: Understanding the Units
Before we begin the conversion, let's clarify the units involved:
Centimeter (cm): This is a unit of length in the metric system. Think of it as a small unit – roughly the width of your pinky finger. 100 centimeters make up one meter (a meter is roughly the height of a kitchen counter).
Inch (in): This is a unit of length in the imperial system. An inch is approximately the length of your thumb from the knuckle to the tip.
Foot (ft): This is another imperial unit. One foot is equal to 12 inches. Think of a ruler – a standard ruler is usually 12 inches long, or one foot.
Section 2: The Conversion Factor
The key to converting between centimeters and inches (and subsequently, feet) is the conversion factor. This is the ratio that tells us how many centimeters are in one inch. This factor is approximately:
1 inch ≈ 2.54 centimeters
The symbol "≈" means "approximately equal to". This is because the conversion isn't perfectly precise, but it's accurate enough for most everyday purposes.
Section 3: Converting Centimeters to Inches
Now, let's convert 165 cm to inches. We'll use the conversion factor:
1. Set up the equation: We want to find out how many inches are in 165 cm. We can set this up as a simple proportion:
```
x inches / 165 cm = 1 inch / 2.54 cm
```
Here, 'x' represents the number of inches we want to find.
2. Solve for x: To solve for 'x', we cross-multiply:
```
x inches 2.54 cm = 165 cm 1 inch
```
This simplifies to:
```
x inches = 165 cm / 2.54 cm/inch
```
3. Calculate: Divide 165 by 2.54:
```
x ≈ 64.96 inches
```
Therefore, 165 cm is approximately 64.96 inches.
Section 4: Converting Inches to Feet and Inches
We now have the length in inches (approximately 64.96 inches), but it's more practical to express this in feet and inches. Since there are 12 inches in a foot, we can divide the total inches by 12 to find the number of feet:
1. Divide by 12:
```
64.96 inches / 12 inches/foot ≈ 5.41 feet
```
This tells us there are approximately 5 feet.
2. Find the remaining inches: To find the remaining inches, we calculate the remainder after dividing by 12:
```
0.41 feet 12 inches/foot ≈ 4.92 inches
```
Therefore, 64.96 inches is approximately 5 feet and 4.92 inches. We can round this to 5 feet and 5 inches for practical purposes.
Section 5: Recap
To summarize, we've converted 165 centimeters to feet and inches using the following steps:
1. Converted centimeters to inches: 165 cm / 2.54 cm/inch ≈ 64.96 inches
2. Converted inches to feet: 64.96 inches / 12 inches/foot ≈ 5.41 feet
3. Calculated remaining inches: 0.41 feet 12 inches/foot ≈ 4.92 inches
4. Final result (rounded): Approximately 5 feet and 5 inches.
Section 6: Frequently Asked Questions (FAQs)
1. Is the conversion factor of 2.54 exact?
