Cuanto es 168 cm en pies y pulgadas? A Beginner's Guide to Metric-Imperial Conversion
Many of us live in a world where we encounter both metric (centimeters, meters, kilometers) and imperial (inches, feet, yards, miles) systems of measurement. Knowing how to convert between these systems can be incredibly helpful, especially when comparing heights, clothing sizes, or even building projects. This article will guide you through converting 168 centimeters (cm) into feet and inches, explaining the process in a simple, step-by-step manner suitable for beginners.
Understanding the Units
Before we begin the conversion, let's understand the units involved:
Centimeter (cm): A unit of length in the metric system. Think of it as a little less than half an inch. Your pinky finger is probably about 1 cm wide.
Inch (in): A unit of length in the imperial system. There are 12 inches in a foot. Imagine the length of your thumb – that's roughly an inch.
Foot (ft): A unit of length in the imperial system. Think of the length of your average adult shoe. There are 12 inches in one foot.
Our goal is to translate 168 cm from the metric system to feet and inches in the imperial system.
Step-by-Step Conversion: 168 cm to Feet and Inches
We'll break down the conversion into manageable steps using a straightforward approach:
Step 1: Converting Centimeters to Inches
The fundamental conversion factor between centimeters and inches is approximately 1 inch = 2.54 cm. This means that there are roughly 2.54 centimeters in every inch. To convert 168 cm to inches, we divide the number of centimeters by the conversion factor:
168 cm / 2.54 cm/inch ≈ 66.14 inches
This tells us that 168 cm is approximately equal to 66.14 inches.
Step 2: Converting Inches to Feet and Remaining Inches
Now, we need to convert these inches into feet and the remaining inches. Since there are 12 inches in one foot, we can find out how many feet are in 66.14 inches by dividing by 12:
66.14 inches / 12 inches/foot ≈ 5.51 feet
This means that there are approximately 5 full feet in 66.14 inches.
To find the remaining inches, we look at the decimal part of the previous calculation (0.51). We multiply this by 12 to find the leftover inches:
0.51 feet 12 inches/foot ≈ 6.12 inches
Therefore, the remaining inches are approximately 6.12 inches.
Step 3: Combining the Results
Putting it all together, we find that 168 cm is approximately equal to 5 feet and 6.12 inches. For practical purposes, you might round this to 5 feet and 6 inches.
Real-World Analogy
Imagine you're buying a curtain rod. The instructions say the rod is 168 cm long, but your measurements are in feet and inches. Using our conversion, you know you need a rod approximately 5 feet 6 inches long. This helps you select the correct size.
Recap
To convert 168 centimeters to feet and inches:
1. Convert centimeters to inches: Divide the number of centimeters by 2.54 (168 cm / 2.54 cm/inch ≈ 66.14 inches).
2. Convert inches to feet and remaining inches: Divide the total inches by 12 to get the number of feet. Multiply the decimal part of the result by 12 to get the remaining inches.
3. Combine the results: You now have the equivalent measurement in feet and inches.
