To convert 40 centimeters (cm) to feet, we need to understand the conversion factors between the metric system and the imperial system. The metric system uses meters and centimeters for length, while the imperial system uses feet and inches. Knowing that 1 meter equals 100 centimeters and 1 meter is approximately equal to 3.28084 feet, we can calculate the conversion of 40 cm to feet.
Conversion Process
First, convert 40 centimeters to meters. Since 1 meter = 100 centimeters, 40 cm is 40 / 100 = 0.4 meters. Next, convert meters to feet using the conversion factor 1 meter = 3.28084 feet. Thus, 0.4 meters = 0.4 * 3.28084 feet.
Calculation
The calculation is as follows: 0.4 meters * 3.28084 feet/meter = 1.312336 feet. Rounding to two decimal places, 40 cm is approximately 1.31 feet.
| Unit | Conversion Factor | Result |
|---|---|---|
| Centimeters to Meters | 1 meter = 100 cm | 40 cm = 0.4 meters |
| Meters to Feet | 1 meter = 3.28084 feet | 0.4 meters = 1.312336 feet |
Key Points
- 40 cm is equivalent to 0.4 meters.
- The conversion factor from meters to feet is 1 meter = 3.28084 feet.
- 40 cm converts to approximately 1.31 feet when rounded to two decimal places.
