To convert from US Survey Foot (ft-us) to Centimeter (cm), use the following formula:
Centimeter (cm)
= 1.000002 × 0.3048 × 100× US Survey Foot (ft-us)
= 30.48006096× US Survey Foot (ft-us)
With 0.3048 is the ratio between the base units Meter (m) and Foot (ft).
Let's convert 5 US Survey Foot (ft-us) to Centimeter (cm).
Using the formula:
5 × 30.48006096 = 152.4003048
Therefore, 5 US Survey Foot (ft-us) is equal to 152.4003048 Centimeter (cm).
How many us survey feet are in one centimeter? One Centimeter (cm) contains 0.032808333333464566667 US Survey Feet (ft-us) — the inverse of the factor above. Multiplying by 30.48006096 takes you from us survey feet to centimeters; multiplying by 0.032808333333464566667 brings you back.
Put in words: one us survey foot equals 30.48006096 centimeters, so the us survey foot is the larger unit of this pair. Converting between them never changes the amount of length being measured — only the size of the unit you count it in.
The US Survey Foot is a unit of length historically used for land surveying in the United States.
It is very close in length to the international foot, equaling approximately 1.000002 international feet (ft). The plural form is US Survey Feet.
The origin of the US Survey Foot dates back to the Mendenhall Order of 1893. This order defined the relationship between the meter and US customary units.
It established that 1 meter is precisely equal to 39.37 inches. From this relationship, the US Survey Foot was derived, defined as 1200/3937 meters.
This definition differs slightly from the international foot, which was established in 1959 and is defined as exactly 0.3048 meters.
To simplify measurements and prevent confusion, the National Institute of Standards and Technology (NIST) and the National Geodetic Survey (NGS) made a critical change.
They officially retired the U.S. Survey Foot on December 31, 2022.
Surveying and mapping applications in the United States will now use the international foot. This critical change helps unify the National Spatial Reference System (NSRS) and prevents costly errors in large-scale projects.
While the difference between a US Survey Foot and an international foot is minuscule—only about two parts per million—it becomes significant over large distances.
For every mile, the discrepancy adds up to approximately 1/8 inch.
This minor error may not be significant for a backyard fence. However, for massive construction projects and infrastructure development, such as bridges that cross state lines, the accumulated error can lead to severe misalignments and costly mistakes.
A centimeter (cm) is a unit of length in the metric system.
It is equal to one hundredth of a meter (0.01 m). The plural form is centimeters.
One of the most crucial facts about the centimeter is its relationship with the inch.
There are exactly 2.54 centimeters in one inch.
This precise conversion factor is essential for global trade, engineering, and daily life. It enables easy and accurate translation between the metric system (used by most of the world) and the imperial system (still used in countries such as the United States).
Gaining a clear understanding of this cm to inch conversion is essential for various tasks, including purchasing clothing and international manufacturing.
The centimeter is a cornerstone of the Centimeter-Gram-Second (CGS) system of units.
This system was an essential precursor to the modern International System of Units (SI).
In the CGS system, the centimeter was the base unit of length, the gram the base unit of mass, and the second the base unit of time.
While less common today, it's still widely used in specific fields of physics, such as astrophysics, for calculating other vital units like force and energy.
To understand how big a centimeter is, it helps to use common items as a useful mental benchmark. This is great for estimating its length without a ruler.
A centimeter is approximately the same width as:
