Understanding the Measurement: Feet, Inches, and Centimeters
Before diving into the conversion process, it’s important to understand the units involved.
What is a Foot?
- The foot (plural: feet) is a unit of length in the imperial system.
- It is primarily used in the United States, the United Kingdom, and some other countries.
- One foot is equal to 12 inches.
What is an Inch?
- The inch is a smaller unit of length in the imperial system.
- It is commonly used for measuring height, small lengths, or dimensions.
- One inch is equal to 2.54 centimeters.
What is a Centimeter?
- The centimeter is a unit of length in the metric system.
- It is widely used around the world, especially in scientific, medical, and everyday measurements.
- One centimeter equals 0.01 meters.
Converting 4'5" to Centimeters: Step-by-Step Process
Converting height from feet and inches to centimeters involves a systematic approach. Here’s a detailed step-by-step guide:
Step 1: Break down the measurement
- The measurement 4'5" indicates 4 feet and 5 inches.
- Convert each part into centimeters separately.
Step 2: Convert feet to centimeters
- Since 1 foot = 12 inches, first, convert feet to inches:
- 4 feet = 4 × 12 = 48 inches
- Convert inches to centimeters:
- 48 inches × 2.54 cm/inch = 121.92 cm
Step 3: Convert inches to centimeters
- Convert the remaining inches:
- 5 inches × 2.54 cm/inch = 12.7 cm
Step 4: Add the two results
- Total height in centimeters:
- 121.92 cm + 12.7 cm = 134.62 cm
Therefore, 4'5" equals approximately 134.62 centimeters.
Practical Applications of the Conversion
Understanding how to convert feet and inches to centimeters is useful in a variety of real-world contexts:
1. Medical and Health Measurements
