Height is a common measurement, and understanding how to convert between different units is a valuable skill. This article focuses on 164 centimeters (cm) and how to convert this measurement into other commonly used units, such as feet and inches. We'll break down the process step-by-step, making it easy for beginners to understand.
Introduction: Why Convert Heights?
Imagine you're looking at a job application that lists a height requirement in feet and inches, but your own height is in centimeters. Or maybe you're comparing your height to someone whose height is given in a different unit. Knowing how to convert between different height units allows you to seamlessly compare and understand measurements regardless of the unit used. This article will help you master this conversion process for 164 cm.
Section 1: Understanding Centimeters (cm)
The centimeter is a unit of length in the metric system. The metric system is a decimal system, meaning it's based on powers of 10, making conversions relatively straightforward. Think of a centimeter as a little less than half an inch. A ruler typically has markings showing centimeters, usually in intervals of 1 cm. Imagine stacking 100 one-centimeter blocks; the resulting stack would be one meter (m) tall – a meter is about the height of a kitchen counter.
Section 2: Understanding Feet and Inches (ft and in)
Feet and inches are part of the imperial system of measurement, primarily used in the United States and a few other countries. A foot (ft) is approximately 30.48 centimeters. An inch (in) is one-twelfth of a foot, meaning there are 12 inches in one foot. Imagine a standard ruler; each inch is divided into smaller increments.
Section 3: Converting 164 cm to Feet and Inches
Now, let's convert 164 cm to feet and inches. We'll do this in two steps:
Step 1: Converting Centimeters to Feet
First, we need to figure out how many feet are in 164 centimeters. We know that 1 foot is approximately 30.48 cm. To find the number of feet, we divide the total centimeters by the number of centimeters in one foot:
164 cm / 30.48 cm/ft ≈ 5.38 ft
This means 164 cm is approximately 5.38 feet. However, this isn't a very practical answer as we rarely use decimal fractions of feet in everyday life.
Step 2: Converting the Decimal Portion of Feet to Inches
The 0.38 ft represents the fractional part of a foot. To convert this to inches, we multiply it by 12 (since there are 12 inches in a foot):
0.38 ft 12 in/ft ≈ 4.56 in
Therefore, 0.38 feet is approximately 4.56 inches.
Step 3: Combining the Results
Combining the whole number of feet (5) and the inches (4.56), we find that 164 cm is approximately 5 feet and 4.56 inches. Rounding to the nearest half-inch for practical purposes, we can say 164 cm is approximately 5 feet and 4.5 inches.
Section 4: Using Online Converters
Fortunately, we don't always have to do these calculations manually. Many online converters are available. Simply search for "cm to feet inches converter" on the internet, enter 164 cm, and the converter will instantly provide the equivalent measurement in feet and inches. These tools are convenient and reduce the chance of calculation errors.
Section 5: Real-World Application
Understanding height conversions is useful in many situations:
Shopping for clothes online: Many clothing websites list sizing based on height.
Medical applications: Doctors often record height in both metric and imperial units.
Comparing heights with others: Easily compare your height to others, regardless of the units they use.
Construction and design: Precise measurements are crucial in construction, and converting between units is essential.
Recap:
We've learned that 164 cm is approximately 5 feet and 4.5 inches. We covered the basics of the metric and imperial systems, and we learned how to convert between centimeters and feet and inches, both manually and using online tools. Remember, the decimal portions in these conversions are often rounded for practical use.
Frequently Asked Questions (FAQs):
1. Is there a precise conversion between cm and feet/inches? No, the conversion is approximate because the relationship between cm and feet/inches isn't a whole number.
2. Why are there two different systems of measurement? Historically, different systems evolved independently, and the imperial system remains in use in some countries due to inertia and established practices.
3. Can I convert other lengths besides 164 cm using the same method? Yes, the method described above applies to any length in centimeters. Simply replace 164 with the desired number of centimeters and follow the same steps.
4. Are online converters always accurate? Most reputable online converters are very accurate, but it's always a good idea to understand the underlying conversion principles to check the results if necessary.
5. What if I need to convert feet and inches back into centimeters? You would reverse the process. First, convert feet to inches (multiply by 12), add the remaining inches, and then multiply the total inches by 2.54 (since 1 inch is approximately 2.54 cm).
