What is 164cm in Feet? A Beginner's Guide to Unit Conversion
Many of us live in a world where we encounter different units of measurement every day. While some countries primarily use the metric system (meters, centimeters, kilograms), others rely on the imperial system (feet, inches, pounds). This often leads to confusion when we need to convert between these systems. This article will guide you through the process of converting 164 centimeters (cm) into feet, explaining the steps in a clear and simple manner. We’ll tackle this seemingly complex task by breaking it down into easy-to-understand chunks.
Section 1: Understanding the Units
Before we begin the conversion, let's understand the units involved:
Centimeter (cm): This is a unit of length in the metric system. Imagine a centimeter as roughly the width of your thumb. Ten centimeters equal one decimeter, and 100 centimeters equal one meter.
Meter (m): This is the base unit of length in the metric system. Think of a meter as roughly the height of a kitchen counter or a little taller than a baseball bat.
Foot (ft): This is a unit of length in the imperial system. Imagine a foot as the length of your foot (naturally!). A foot is approximately 12 inches long. The foot is also a common unit used for measuring height.
Inch (in): This is a smaller unit of length in the imperial system. Imagine an inch as the width of a standard adult's thumb knuckle. Twelve inches make up one foot.
Section 2: The Conversion Factor
To convert centimeters to feet, we need a conversion factor. This factor tells us the relationship between the two units. We know that:
1 inch ≈ 2.54 centimeters
This "≈" symbol means "approximately equal to" because the conversion isn't perfectly precise, but it's close enough for most everyday purposes. This means that one inch is a little more than two and a half centimeters.
Since there are 12 inches in a foot, we can also say:
Now, let's convert 164 centimeters to feet using the conversion factor we just established:
1. Divide by the conversion factor: We know that 1 foot is approximately 30.48 centimeters. Therefore, to find out how many feet are in 164 centimeters, we divide 164 by 30.48:
164 cm / 30.48 cm/foot ≈ 5.38 feet
Therefore, 164 centimeters is approximately 5.38 feet.
Let’s break this down with a real-world analogy. Imagine you have a long piece of string that measures 164 centimeters. You want to know its length in feet. You would use a ruler marked in feet and inches to measure the string. The measurement would show approximately 5 feet and a bit more, representing that fraction of a foot, which we found to be 0.38.
Section 4: Understanding Decimal Remainders
The result of our conversion (5.38 feet) includes a decimal part (0.38). This decimal represents a portion of a foot. To convert this decimal part into inches, we can use the following calculation:
0.38 feet 12 inches/foot ≈ 4.56 inches
So, 164 centimeters is approximately 5 feet and 4.56 inches. Rounding to the nearest inch, we can say 164 centimeters is roughly 5 feet and 5 inches.
Section 5: Using Online Converters
While understanding the conversion process is valuable, you can also use online converters for quick and easy results. Many websites and apps offer these tools; simply enter the value in centimeters, and the converter will provide the equivalent in feet and inches. This is a useful method for checking your manual calculations or for quickly performing conversions when accuracy to several decimal places isn't critical.
Recap
We've learned that 164 centimeters is approximately equal to 5 feet and 5 inches. We achieved this by using the conversion factor that relates centimeters and feet. Remember, it's crucial to understand the units and the conversion factor to perform this type of calculation successfully.
FAQs
1. Why is the conversion not exact? The conversion is approximate because the relationship between inches and centimeters (1 inch ≈ 2.54 cm) is not a whole number. This introduces a small degree of imprecision in the final result.
2. Can I convert centimeters to inches directly? Yes, you can. Using the conversion factor 1 inch ≈ 2.54 cm, you can divide the number of centimeters by 2.54 to get the equivalent in inches. Then, you can convert inches to feet by dividing by 12.
3. What if I need a more precise conversion? For applications requiring high precision, use the conversion factor 1 inch = 2.54 cm exactly, and carry out the calculation using a calculator capable of handling more decimal places.
4. Are there any other units of length I should know? Yes, other common units include millimeters (smaller than centimeters), kilometers (larger than meters), yards, and miles (used in the imperial system).
5. Where can I find more practice problems? Many websites and textbooks offer practice problems on unit conversion. Practicing these problems will help you solidify your understanding of the process.
Note: Conversion is based on the latest values and formulas.
