Understanding height conversions is crucial in various contexts. Whether you're applying for a job with height restrictions, comparing your height to others internationally, or simply satisfying your curiosity, knowing how to convert centimeters to feet is a valuable skill. This article will specifically address the question: how tall is 173cm in feet, and will explore the common challenges and questions associated with this conversion.
Understanding the Metric and Imperial Systems
Before diving into the conversion, let's briefly understand the two systems involved: the metric system (using centimeters) and the imperial system (using feet and inches). The metric system is based on powers of 10, making conversions relatively straightforward. The imperial system, however, is less consistent, with varied relationships between units. This difference often leads to confusion during conversions.
The Conversion Factor: Centimeters to Inches and Feet
The fundamental conversion factor is: 1 inch = 2.54 centimeters. This means we first need to convert centimeters to inches before converting to feet (since 1 foot = 12 inches). This two-step process is necessary due to the inconsistency between the systems.
Step-by-Step Conversion of 173cm to Feet and Inches
Step 1: Converting Centimeters to Inches:
To convert 173 centimeters to inches, we use the conversion factor:
173 cm (1 inch / 2.54 cm) = 68.11 inches (approximately)
Step 2: Converting Inches to Feet and Inches:
Since there are 12 inches in a foot, we divide the total inches by 12 to find the number of feet and the remaining inches:
68.11 inches / 12 inches/foot = 5.67 feet
This means 68.11 inches is equal to 5 feet and 0.67 inches. To convert the decimal part of a foot (0.67 feet) to inches, we multiply by 12:
0.67 feet 12 inches/foot ≈ 8 inches
Therefore, 173 cm is approximately 5 feet and 8 inches.
Addressing Common Challenges and Errors
A common mistake is using an inaccurate conversion factor or rounding off too early in the calculation, leading to significant inaccuracies. It's crucial to use the precise conversion factor (2.54 cm = 1 inch) and retain sufficient decimal places during intermediate calculations to minimize errors. Another common challenge involves understanding the remaining fractional part after converting inches to feet. Remember to multiply the decimal part by 12 to get the remaining inches.
Utilizing Online Conversion Tools
While manual calculations are valuable for understanding the process, various online conversion tools offer a quick and convenient way to convert between centimeters and feet. These tools often provide accurate results instantly, saving time and effort. However, it's always advisable to double-check the results with a manual calculation, especially when dealing with critical applications.
Beyond the Numbers: Practical Applications
Understanding height conversions is beneficial in numerous scenarios. For instance:
International comparisons: Height measurements are often expressed differently in different countries. This conversion knowledge allows for easy comparison.
Clothing and apparel: Online clothing retailers may list sizes in centimeters, requiring conversion to ensure the correct fit.
Healthcare: Accurate height measurements are essential in medical assessments, requiring precise conversions for record-keeping and analysis.
Job applications: Some professions may specify height requirements, mandating conversion from one system to another.
Summary
Converting 173cm to feet involves a two-step process: converting centimeters to inches using the factor 2.54 cm/inch, and then converting inches to feet and inches. 173 cm is approximately 5 feet and 8 inches. Accuracy is crucial, necessitating the use of the precise conversion factor and careful attention to rounding. While online tools are readily available, understanding the underlying conversion principles remains vital.
FAQs
1. Is 173cm considered tall? The perception of "tall" is subjective and varies by population and gender. However, 5 feet 8 inches is generally considered above average height for women and average for men in many populations.
2. How can I 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 the total inches by 2.54 to get centimeters.
3. Are there any significant differences in conversion results using different online calculators? Reputable online calculators should provide consistent results. Discrepancies might arise from rounding differences or minor variations in the conversion factor used.
4. What if I need to convert centimeters to feet and inches for a medical record? Extreme precision is essential in healthcare. Retain as many decimal places as possible during the conversion and double-check your calculations.
5. Can I use a simple rule of thumb for quick estimations? While rough estimations can be helpful, for accurate results, always rely on the precise conversion factor of 2.54 cm per inch. Simple rules of thumb can introduce significant errors.
