What Is The Height In Meters Of A 5'4 Person?4. What Is The Mass Of A 125 Lb. Person In Kilograms?5. Which Is Greater: 59 Miles Or 64 Km?
Introduction
In everyday life, we often encounter measurements in different units, such as feet and inches for height, pounds for weight, and miles for distance. However, in scientific and technical contexts, it's essential to convert these units to a standard system, such as the metric system. In this article, we'll explore three common conversion problems: converting a person's height from feet and inches to meters, converting a person's weight from pounds to kilograms, and comparing a distance in miles to a distance in kilometers.
Converting Height from Feet and Inches to Meters
To convert a person's height from feet and inches to meters, we need to follow these steps:
- Convert feet to meters: There are 0.3048 meters in 1 foot. So, to convert feet to meters, we multiply the number of feet by 0.3048.
- Convert inches to meters: There are 0.0254 meters in 1 inch. So, to convert inches to meters, we multiply the number of inches by 0.0254.
- Add the two values: Once we have the values in meters, we add them together to get the total height in meters.
Let's apply this formula to a person who is 5'4" tall. First, we convert the feet to meters:
5 feet x 0.3048 meters/foot = 1.524 meters
Next, we convert the inches to meters:
4 inches x 0.0254 meters/inch = 0.1016 meters
Now, we add the two values together:
1.524 meters + 0.1016 meters = 1.6256 meters
Therefore, a person who is 5'4" tall is approximately 1.6256 meters tall.
Converting Weight from Pounds to Kilograms
To convert a person's weight from pounds to kilograms, we need to follow these steps:
- Multiply the weight in pounds by 0.453592: This will give us the weight in kilograms.
Let's apply this formula to a person who weighs 125 pounds. We multiply the weight in pounds by 0.453592:
125 pounds x 0.453592 kilograms/pound = 56.699 kilograms
Therefore, a person who weighs 125 pounds weighs approximately 56.699 kilograms.
Comparing Distance in Miles to Distance in Kilometers
To compare a distance in miles to a distance in kilometers, we need to follow these steps:
- Convert miles to kilometers: There are 1.60934 kilometers in 1 mile. So, to convert miles to kilometers, we multiply the number of miles by 1.60934.
- Compare the two values: Once we have the values in kilometers, we can compare them to determine which is greater.
Let's apply this formula to a distance of 59 miles. We convert the miles to kilometers:
59 miles x 1.60934 kilometers/mile = 94.545 kilometers
Now, we compare the two values:
59 miles = 94.545 kilometers 64 kilometers = 39.626 miles
Therefore, 64 kilometers is less than 59 miles.
Conclusion
In conclusion, converting units is an essential skill in mathematics and science. By following the steps outlined in this article, we can convert a person's height from feet and inches to meters, convert a person's weight from pounds to kilograms, and compare a distance in miles to a distance in kilometers. Remember to always use the correct conversion factors and to double-check your calculations to ensure accuracy.

Introduction
In our previous article, we explored the basics of unit conversion, including converting a person's height from feet and inches to meters, converting a person's weight from pounds to kilograms, and comparing a distance in miles to a distance in kilometers. However, we know that there are many more questions and scenarios that require unit conversion. In this article, we'll answer some of the most frequently asked questions about unit conversion.
Q: How do I convert a temperature from Fahrenheit to Celsius?
A: To convert a temperature from Fahrenheit to Celsius, use the following formula:
°C = (°F - 32) × 5/9
For example, to convert 100°F to Celsius, we would:
°C = (100 - 32) × 5/9 °C = 37.78°C
Q: How do I convert a volume from gallons to liters?
A: To convert a volume from gallons to liters, use the following conversion factor:
1 gallon = 3.78541 liters
For example, to convert 5 gallons to liters, we would:
5 gallons × 3.78541 liters/gallon = 18.92705 liters
Q: How do I convert a speed from miles per hour to kilometers per hour?
A: To convert a speed from miles per hour to kilometers per hour, use the following conversion factor:
1 mile per hour = 1.60934 kilometers per hour
For example, to convert 60 miles per hour to kilometers per hour, we would:
60 miles per hour × 1.60934 kilometers per hour/mile per hour = 96.5644 kilometers per hour
Q: How do I convert a time from hours to minutes?
A: To convert a time from hours to minutes, use the following conversion factor:
1 hour = 60 minutes
For example, to convert 2 hours to minutes, we would:
2 hours × 60 minutes/hour = 120 minutes
Q: How do I convert a distance from kilometers to miles?
A: To convert a distance from kilometers to miles, use the following conversion factor:
1 kilometer = 0.621371 miles
For example, to convert 100 kilometers to miles, we would:
100 kilometers × 0.621371 miles/kilometer = 62.1371 miles
Q: How do I convert a weight from kilograms to pounds?
A: To convert a weight from kilograms to pounds, use the following conversion factor:
