Understanding different units of measurement is a crucial life skill, impacting everything from cooking and crafting to international travel and even healthcare. While the metric system (using centimeters, meters, etc.) is prevalent globally, the imperial system (using feet and inches) remains common in certain regions, particularly the United States. Knowing how to convert between these systems is therefore essential for seamless communication and accurate measurements. This article will guide you through the process of converting 168 centimeters to feet and inches, breaking down the method step-by-step and addressing common questions along the way.
I. Understanding the Metric and Imperial Systems
Before diving into the conversion, let's quickly revisit the fundamental units:
Metric System: Based on powers of 10, making conversions relatively straightforward. The basic unit of length is the meter (m), with centimeters (cm) being one-hundredth of a meter (1 m = 100 cm).
Imperial System: A more complex system with irregular relationships between units. The basic unit of length is the foot (ft), with 12 inches (in) making up one foot (1 ft = 12 in). Yards and miles are further units within the system.
The disparity between these systems necessitates a conversion factor to move seamlessly between them.
II. The Conversion Factor: Centimeters to Inches
The key to converting 168 cm to feet and inches lies in understanding the conversion factor between centimeters and inches. One inch is approximately equal to 2.54 centimeters. This means:
1 inch ≈ 2.54 cm
Therefore, to convert centimeters to inches, we divide the number of centimeters by 2.54:
Inches = Centimeters / 2.54
Let's apply this to our example:
Inches = 168 cm / 2.54 cm/in ≈ 66.14 inches
III. Converting Inches to Feet and Inches
Now that we've converted 168 cm to approximately 66.14 inches, we need to express this measurement 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:
Feet = Total inches / 12
Feet = 66.14 in / 12 in/ft ≈ 5.51 ft
This tells us we have approximately 5 feet. To find the remaining inches, we subtract the whole number of feet (5) multiplied by 12 from the total inches:
Remaining inches = Total inches - (Feet 12)
Remaining inches = 66.14 in - (5 ft 12 in/ft) = 66.14 in - 60 in = 6.14 in
Therefore, 168 cm is approximately equal to 5 feet and 6.14 inches. For practical purposes, we would often round this to 5 feet and 6 inches.
IV. Practical Application and Precision
The conversion above demonstrates a general approach. However, the precision needed depends on the context. For example:
Tailoring: High precision is required. Rounding to the nearest 1/8th of an inch might be necessary.
Construction: Precision is important, but less stringent than tailoring. Rounding to the nearest inch might suffice.
Everyday estimations: Rounding to the nearest inch or even half-inch is often acceptable.
The degree of rounding affects the final result. Always consider the level of accuracy needed for your specific application.
V. Using Online Converters and Calculators
While understanding the conversion process is beneficial, using online converters or calculators can significantly simplify the process, particularly when dealing with multiple conversions or complex calculations. Many websites and apps offer quick and accurate conversions between metric and imperial units. These tools are particularly helpful for checking your work or performing rapid conversions for various scenarios.
VI. Beyond 168cm: Mastering the Conversion
The principles demonstrated here can be applied to any centimeter-to-feet-and-inches conversion. Simply replace 168 cm with the desired value and follow the same steps. Remember the conversion factor (1 inch ≈ 2.54 cm) and the relationship between feet and inches (1 ft = 12 in). Practicing with different values will solidify your understanding and improve your proficiency.
Summary:
Converting 168 cm to feet and inches involves:
1. Dividing the centimeters by 2.54 to get inches.
2. Dividing the total inches by 12 to get feet.
3. Subtracting the whole number of feet (multiplied by 12) from the total inches to find the remaining inches.
The result for 168 cm is approximately 5 feet and 6 inches. However, the precision needed varies depending on the context.
FAQs:
1. Why is the conversion not exact? The conversion factor (1 inch ≈ 2.54 cm) is an approximation. A more precise conversion requires more significant figures, leading to slightly different results.
2. Can I use a calculator for this conversion? Yes, using a calculator or online converter is highly recommended for speed and accuracy, especially for complex conversions.
3. What if I need to convert feet and inches back to centimeters? Reverse the process. Multiply the feet by 12 to get total inches, add the remaining inches, and then multiply by 2.54 to get centimeters.
4. Are there other online resources to help with unit conversions? Yes, numerous websites and apps offer unit conversion tools for various units, including length, weight, volume, and temperature.
5. Is there a formula I can use to remember this conversion? While there isn't a single compact formula, remembering the conversion factor (1 in ≈ 2.54 cm) and the relationship between feet and inches (1 ft = 12 in) allows you to derive the necessary steps for any conversion.
Note: Conversion is based on the latest values and formulas.
