To convert 120 cm to feet, we first need to understand the conversion factors between centimeters and feet. There are 100 centimeters in a meter and 3.2808 feet in a meter. Therefore, to convert centimeters to feet, we divide the number of centimeters by 100 to get meters, and then divide the result by 0.3048 (since 1 foot = 0.3048 meters) or multiply by 3.2808 (the conversion factor from meters to feet).
Calculation Process
The calculation to convert 120 cm to feet involves the following steps:
1. Convert 120 cm to meters: 120 cm / 100 = 1.2 meters.
2. Convert meters to feet: 1.2 meters * 3.2808 feet/meter = 3.937008 feet.
This result can be rounded for practical purposes. Therefore, 120 cm is approximately equal to 3.94 feet when rounded to two decimal places.
Understanding Conversion Factors
It’s essential to grasp the conversion factors between different units of measurement. The factor to convert meters to feet (3.2808 feet per meter) is crucial for converting between the metric system and imperial or US customary units. This knowledge is beneficial in various fields, including construction, international trade, and scientific research, where measurements often need to be communicated across different systems.
