Understanding Length Units for Our Length Converter Tools
Metric System Length Units
The metric system is the standard system of measurement used in most countries worldwide. It’s based on powers of 10, making conversions between units simple.
- Kilometer (km): 1,000 meters, used for measuring long distances
- Meter (m): The base unit of length in the metric system
- Centimeter (cm): 1/100 of a meter, used for everyday measurements
- Millimeter (mm): 1/1000 of a meter, used for precise measurements
Imperial/US Customary Length Units
The imperial and US customary systems are primarily used in the United States and a few other countries. These systems have historical origins and use different conversion factors.
- Mile (mi): 5,280 feet, used for measuring long distances
- Yard (yd): 3 feet or 36 inches
- Foot (ft): 12 inches, commonly used in construction and height measurements
- Inch (in): The smallest commonly used unit in this system
Common Length Converter Tools Conversion Factors
Meters to Feet
ft = m × 3.28084
Feet to Meters
m = ft × 0.3048
Centimeters to Inches
in = cm × 0.393701
Inches to Centimeters
cm = in × 2.54
Kilometers to Miles
mi = km × 0.621371
Miles to Kilometers
km = mi × 1.60934
Frequently Asked Questions
Why are there different systems of measurement?
Different measurement systems developed independently across various cultures and regions throughout history. The metric system was created during the French Revolution to standardize measurements, while the imperial system evolved from earlier English units.
Which countries use the metric system?
Almost all countries in the world officially use the metric system. The United States, Myanmar (Burma), and Liberia are the only countries that have not fully adopted the metric system as their official system of weights and measures.
How accurate are these conversions?
Our converters use standard conversion factors that are accurate to multiple decimal places. For most everyday purposes, these conversions are more than accurate enough. For scientific or highly precise work, we recommend using the exact conversion factors.
What is the smallest unit of length?
In everyday use, millimeters or micrometers are the smallest commonly used units. In scientific contexts, much smaller units like nanometers (nm), picometers (pm), and even smaller units are used to measure atomic and subatomic distances.
