Understanding different units of measurement can be tricky, especially when it comes to height. While centimeters (cm) are widely used internationally, feet (ft) and inches (in) remain prevalent in certain regions, particularly the United States. This article will clearly explain how to convert 168 centimeters into feet and inches, breaking down the process step-by-step to ensure a complete understanding.
1. Understanding the Units: Centimeters and Feet
Before we begin the conversion, let's clarify the units involved. A centimeter (cm) is a unit of length in the metric system, with 100 centimeters equaling one meter. A foot (ft) is a unit of length in the imperial system, with 12 inches making up one foot. The key to conversion lies in understanding the relationship between these two systems. One meter is approximately equal to 3.28 feet.
2. The Conversion Process: From Centimeters to Feet
To convert 168 centimeters to feet, we need to use a conversion factor. Since 1 meter equals approximately 3.28 feet, and there are 100 centimeters in a meter, we can establish the following relationship:
1 cm ≈ 0.0328 ft (This is derived by dividing 3.28 feet by 100 cm)
Now, we can simply multiply 168 cm by this conversion factor:
168 cm 0.0328 ft/cm ≈ 5.51 ft
Therefore, 168 centimeters is approximately 5.51 feet.
3. Refining the Conversion: Inches for Greater Accuracy
The conversion above provides a reasonable approximation. However, for greater precision, we can calculate the remaining fraction of a foot in inches. The 0.51 feet represents a portion of a foot. To convert this to inches, we utilize the fact that 1 foot equals 12 inches:
0.51 ft 12 in/ft ≈ 6.12 in
So, the more precise conversion of 168 cm is approximately 5 feet and 6.12 inches. For practical purposes, you might round this to 5 feet and 6 inches.
4. Practical Examples and Applications
Understanding this conversion is useful in various situations:
Online Shopping: Many international online stores use centimeters for clothing sizes. Knowing how to convert to feet and inches ensures you order the correct size.
International Travel: If you're traveling to a country using the imperial system, you'll need to be able to convert your height for things like rental car requirements or medical forms.
Comparing Heights: If you're comparing your height to someone else's, knowing the conversion allows for easy comparison regardless of the unit used.
Medical Records: Medical records may use either system. Converting between the two allows for accurate information transfer and comparison.
5. Actionable Takeaways and Key Insights
The key takeaway is that converting between centimeters and feet involves a two-step process, first converting to feet and then refining the result to inches for greater accuracy. Remember the approximate conversion factor of 1 cm ≈ 0.0328 ft, and that 1 foot equals 12 inches. Using a calculator can significantly simplify the process, especially for more complex conversions. Always round your answers to a practical level of precision based on the context.
FAQs
1. Q: Is the conversion factor of 1 cm ≈ 0.0328 ft exact?
A: No, it's an approximation. The actual conversion factor is closer to 0.0328084 ft, but for most purposes, 0.0328 ft is sufficiently accurate.
2. Q: Can I use online converters for this type of conversion?
A: Yes, many online converters are readily available for quick and accurate conversions between centimeters and feet.
3. Q: Why are there two different systems of measurement?
A: The metric system (centimeters) is a decimal system, making calculations simpler. The imperial system (feet and inches) evolved historically and is still used in some countries.
4. Q: What if I want to convert a different height in centimeters to feet and inches?
A: You would use the same process outlined above. Simply multiply the height in centimeters by 0.0328 to get the approximate height in feet, and then multiply the decimal portion of the feet by 12 to obtain the inches.
5. Q: Is it always necessary to convert to inches after converting to feet?
A: No. The level of precision needed depends on the context. For some purposes, the approximation in feet alone might suffice. However, for accurate measurements, converting to inches is recommended.
