What is 145cm in feet
The Correct Answer and Explanation is:
To convert centimeters to feet, we can use the conversion factor that 1 inch equals 2.54 centimeters, and there are 12 inches in a foot. Thus, 1 foot is equal to 30.48 centimeters.
To convert 145 centimeters to feet, we can follow these steps:
- Convert centimeters to inches:
[
\text{Inches} = \frac{\text{Centimeters}}{2.54}
]
Substituting 145 centimeters:
[
\text{Inches} = \frac{145}{2.54} \approx 57.09 \text{ inches}
] - Convert inches to feet:
[
\text{Feet} = \frac{\text{Inches}}{12}
]
Substituting 57.09 inches:
[
\text{Feet} = \frac{57.09}{12} \approx 4.76 \text{ feet}
]
Thus, 145 centimeters is approximately 4.76 feet.
Detailed Explanation
- Understanding Units:
The centimeter (cm) is a metric unit of length, while the foot (ft) is an imperial unit. Converting between these two systems is essential in many fields, including science, engineering, and everyday life, where different countries use different measurement systems. - Conversion Factors:
To facilitate conversion, we utilize known conversion factors:
- 1 inch = 2.54 centimeters
- 1 foot = 12 inches
Therefore, 1 foot is ( 30.48 ) centimeters (calculated as ( 12 \text{ inches} \times 2.54 \text{ cm/inch} )).
- Performing Calculations:
We first convert centimeters to inches because the conversion to feet is straightforward once we have inches. By dividing the centimeter measurement by 2.54, we determine the equivalent number of inches. Then, by dividing this result by 12, we convert inches to feet. - Practical Applications:
Understanding how to convert measurements is crucial in various scenarios, such as height measurement in sports, construction specifications, and international travel, where differing systems might cause confusion.
In conclusion, 145 cm converts to approximately 4.76 feet, illustrating the importance of unit conversions in everyday contexts.
