Centimeters (cm) and feet (ft) are both units that measure length, but one comes from the metric system and the other from the imperial and US customary systems.
Converting between these units is common in construction, healthcare, and even everyday measurements. So, how many feet is 123 cm? Let’s find out.
The conversion factor and formula
When you’re converting between measurement systems, it’s important to know the conversion factor, which is the number you’ll multiply or divide by to convert from one unit to another.
Here’s the relationship between centimeters and feet:
- One foot equals 30.48 centimeters.
- One centimeter equals approximately 0.032808399 feet.
So, to convert from centimeters to feet, you’ll use this formula:
Feet = Centimeters / 30.48
How to convert 123 cm to feet
To convert 123 cm into feet, you can use the following formula:
123 cm ÷ 30.48 = 4.03543307 feet
For practical purposes, you’ll likely want to round that number. So, 123 centimeters is approximately 4.04 feet.
Keep in mind that this is an approximate value. If you require a precise measurement, it’s best to use the unrounded number or a specialized conversion tool.
How to convert 123 cm to feet and inches
When converting centimeters to feet and inches, it’s helpful to break down the feet into whole numbers. In this case, 123 cm is a little over 4 feet.
To calculate the remaining inches, we need to account for the decimal portion of the feet. Here’s how:
0. 03543307 feet 12 inches/foot = 0.42519684 inches
For practical purposes, you can round that to 0.43 inches.
So, 123 cm is approximately 4 feet and 0.43 inches.
When is it useful to convert centimeters to feet?
