Calculate Length in CM, Meters, & Feet: Measurement Guide
Reviewed by Umesh Upadhyay MCA
Whether you are measuring the length of an object, arranging space, or converting between units of length, it is important to measure it accurately. The units we will use for length measurement and conversion are centimeters (cm), meters (m), and feet (ft), which are units that can be important regardless of what you measure.
Measurement of each unit has a specific purpose. Centimeters and meters are used with the metric system, while feet are used with the imperial system. In this article, we will demonstrate how to measure length, highlight the differences in measuring methods, and show how to convert units of length easily and accurately.
What are Length Measurement Units?
Length units serve as reference points for the distance between two regions. The metric system and the imperial or customary system are the two most recognized systems. The meter (m) is also the standard unit of length in the International System of Units (SI). Among the more commonly used units of length are the kilometer (km), centimeter (cm), and millimeter (mm). Popular units in the imperial and customary systems are the inch (in), foot (ft), yard (yd), and mile (mi).
How to Calculate Length in CM
If you want to measure the length in cm, you should follow these steps:
Step 1: Use a measuring device such as a ruler, measuring tape, or scale, which has markings for centimeters.
Step 2: Place the measuring device along the length of the object.
Step 3: Record that number at the end of the object – that is, the length in cm.
Step 4: If you have measured in meters, to convert to centimeters, multiply by 100.
Formula: Length (cm) = Length (m) × 100
Step 5: If you have measured in feet, then to convert to centimeters, multiply by 30.48.
Formula: Length (cm) = Length (ft) × 30.48
How to Calculate Length in Meters
To find length in meters, measure with a tape or ruler measuring in meters. If your measure is in centimeters, do a division by 100 because a meter has 100 centimeters. In conversions from feet, multiply the length in feet by 0.3048 because 1 foot equals 0.3048 meters. The equations are: Length (m) = Length (cm) ÷ 100 and Length (m) = Length (ft) × 0.3048. This assists you in getting the correct measurements in meters for any object or distance.
How to Calculate Length in Feet
There are two common methods to calculate length in feet: direct measurement and a unit converter. Here are the methods explained below:
Method 1: Direct Measurement
- Use a Measuring Tape: Grab a measuring tape graduated in feet and inches.
- Align with the Object: Put it along the height or length of the object.
- Read the Measurement: Mark the reading at the end—this is the object’s length in feet.
- Convert Inches (if necessary): If your tape has inches, divide by 12 to find feet.
Formula: Length (ft) = Inches ÷ 12
Method Two: Converting from Other Units
- For centimeters: Divide the length in centimeters by 30.48, because there are 30.48 cm in a foot.
Formula: Length (ft) = Length (cm) ÷ 30.48
- For meters: Multiply the length in meters by 3.281 to convert the length to feet.
Formula: Length (ft) = Length (m) × 3.281
- Calculator/Converter: To save time, use a conversion calculator to convert online.
