Understanding the Metric and Imperial Measurement Systems
The Metric System
The metric system is a decimal-based measurement system used by most countries around the world. It is based on units such as meters, centimeters, and millimeters, making it straightforward to convert within the system by moving the decimal point.
- 1 meter (m) = 100 centimeters (cm)
- 1 centimeter = 10 millimeters (mm)
The Imperial System
The imperial system, primarily used in the United States and a few other countries, measures length in feet and inches.
- 1 foot (ft) = 12 inches (in)
- 1 yard = 3 feet
- 1 inch = 2.54 centimeters
Understanding these basic units is essential for accurate conversion between the two systems.
How to Convert 140 cm to Feet and Inches
Step 1: Convert centimeters to inches
Since 1 inch equals 2.54 centimeters, you can convert centimeters to inches by dividing the centimeter value by 2.54.
Calculation:
\[ \text{Inches} = \frac{140\, \text{cm}}{2.54} \approx 55.12\, \text{in} \]
So, 140 centimeters is approximately 55.12 inches.
Step 2: Convert inches to feet and remaining inches
Next, divide the total inches by 12 (since 1 foot = 12 inches) to find out how many feet there are and what remains as extra inches.
Calculation:
\[ \text{Feet} = \left\lfloor \frac{55.12}{12} \right\rfloor = 4\, \text{feet} \]
\[ \text{Remaining inches} = 55.12 - (4 \times 12) = 55.12 - 48 = 7.12\, \text{in} \]
Therefore, 140 cm is approximately 4 feet 7.12 inches.
