Understanding the Metric and Imperial Systems
The Metric System: Centimeters
The metric system is a decimal-based system of measurement used worldwide, especially in scientific contexts. One centimeter (cm) is equal to one hundredth of a meter. It is a small unit commonly used to measure height, length, and width of objects.
The Imperial System: Feet and Inches
In the imperial system, which is primarily used in the United States, height is often expressed in feet and inches. One foot (ft) equals 12 inches (in). To convert centimeters to feet and inches, one needs to understand the relationship between these units.
Conversion of 181 cm to Feet and Inches
The Basic Conversion Formula
The general process of converting centimeters to feet and inches involves:
1. Converting centimeters to inches
2. Converting inches to feet and remaining inches
The formulas are as follows:
- Inches = Centimeters ÷ 2.54
- Feet = Total inches ÷ 12 (integer part)
- Remaining inches = Total inches % 12
Step-by-Step Conversion of 181 cm
Let's perform the conversion step-by-step:
1. Convert 181 cm to inches:
181 cm ÷ 2.54 ≈ 71.2598 inches
2. Determine the number of feet:
71.2598 ÷ 12 ≈ 5.9383 feet
The integer part is 5, which means 5 feet.
3. Calculate remaining inches:
Remaining inches = 71.2598 - (5 × 12) = 71.2598 - 60 = 11.2598 inches
Result:
