173 cm in Inches and Feet: A Beginner's Guide to Metric-Imperial Conversions
Understanding different units of measurement can sometimes feel like navigating a foreign language. This article will guide you through the process of converting 173 centimeters (cm), a metric unit, into inches and feet, units within the imperial system. We'll break down the process step-by-step, using simple explanations and relatable examples.
I. Understanding the Units
Before we begin the conversion, let's clarify the units involved:
Centimeter (cm): This is a unit of length in the metric system. Think of it as a little less than half an inch. Your pinky fingernail is probably about 1 cm wide. The metric system is based on powers of 10, making conversions relatively straightforward.
Inch (in): This is a unit of length in the imperial system. Imagine the width of your thumb – that's roughly an inch. The imperial system uses different, less intuitive relationships between its units, which is why conversions can sometimes seem more complicated.
Foot (ft): This is another imperial unit of length. It's equivalent to 12 inches. Think of a standard ruler – it’s usually 12 inches long, or one foot.
II. Converting Centimeters to Inches
The fundamental conversion factor we need is that 1 inch is approximately equal to 2.54 centimeters. This is the key to unlocking the conversion. To convert 173 cm to inches, we'll use the following formula:
Inches = Centimeters ÷ 2.54
Let's plug in our value:
Inches = 173 cm ÷ 2.54 ≈ 68.11 inches
Therefore, 173 centimeters is approximately 68.11 inches.
III. Converting Inches to Feet
Now that we know 173 cm is about 68.11 inches, we can convert this to feet. Since there are 12 inches in one foot, we use this formula:
Feet = Inches ÷ 12
Let's plug in our value:
Feet = 68.11 inches ÷ 12 ≈ 5.68 feet
So, 173 centimeters is approximately 5.68 feet.
IV. Putting it All Together: A Real-World Analogy
Imagine you're buying a curtain rod for a window that measures 173 cm wide. You go to a store that only lists rod lengths in inches and feet. Using our calculations, you now know you need a rod that's approximately 68.11 inches or 5.68 feet long. To be safe, you might round up to 69 inches or 6 feet to ensure the rod is long enough.
V. Understanding Significant Figures and Rounding
The number of significant figures in a measurement reflects the precision of the measurement. Since we started with 173 cm (three significant figures), it's appropriate to round our answers to a similar level of precision. In our example, we could reasonably round 68.11 inches to 68 inches and 5.68 feet to 5.7 feet. This keeps our answer consistent with the initial precision.
VI. Recap
To summarize, we've learned how to convert 173 cm to both inches and feet. First, we converted centimeters to inches using the conversion factor 1 inch ≈ 2.54 cm, resulting in approximately 68 inches. Then, we converted inches to feet using the conversion factor 1 foot = 12 inches, giving us approximately 5.7 feet. Remember that slight variations can occur due to rounding.
VII. Frequently Asked Questions (FAQs)
1. Why is the conversion factor 2.54 cm ≈ 1 inch? This is a defined conversion factor. It's based on international agreements to standardize measurements.
2. Can I use an online converter instead of doing the calculations manually? Yes, many online converters are readily available to perform these conversions quickly and accurately. However, understanding the process is still valuable.
3. Are there any other units of length in the imperial system? Yes, there are yards (3 feet), miles (5280 feet), and others.
4. What if I need to convert feet back to centimeters? You would reverse the process. First, multiply the number of feet by 12 to get inches, and then multiply the number of inches by 2.54 to get centimeters.
5. Why are there two different systems of measurement? Historically, different systems evolved independently. The metric system is now the internationally preferred system, but the imperial system is still widely used in some countries.
By now, you should have a clearer understanding of how to convert 173 cm into inches and feet. Remember the key conversion factors (1 inch ≈ 2.54 cm and 1 foot = 12 inches) and you'll be able to handle similar conversions confidently. Practice is key – try converting other lengths to solidify your understanding!
