To convert from Decimeter (dm) to US Survey Foot (ft-us), use the following formula:
US Survey Foot (ft-us)
= 110 × 10.3048 × 11.000002× Decimeter (dm)
= 0.32808333333464566667× Decimeter (dm)
With 10.3048 is the ratio between the base units Foot (ft) and Meter (m).
Let's convert 5 Decimeter (dm) to US Survey Foot (ft-us).
Using the formula:
5 × 0.32808333333464566667 = 1.6404166666732283334
Therefore, 5 Decimeter (dm) is equal to 1.6404166666732283334 US Survey Foot (ft-us).
How many decimeters are in one us survey foot? One US Survey Foot (ft-us) contains 3.048006096 Decimeters (dm) — the inverse of the factor above. Multiplying by 0.32808333333464566667 takes you from decimeters to us survey feet; multiplying by 3.048006096 brings you back.
Put in words: one decimeter equals 0.32808333333464566667 us survey feet, so the decimeter is the smaller 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.
A decimeter (dm) is a unit of length in the metric system equal to one-tenth of a meter (0.1 m).
Its plural form is decimeters.
One of the most important uses of the decimeter is in measuring volume.
A cubic decimeter (dm3) is the volume of a cube with edges that are one decimeter long. This connection is beneficial, as one cubic decimeter is precisely equal to one liter (L).
This direct relationship (1 dm3 = 1 L) makes the decimeter a fundamental unit in chemistry and physics for calculating liquid volumes and densities.
The decimeter serves as a convenient intermediate unit between the meter (m) and the centimeter (cm). It provides a practical step in the metric system's base-10 structure.
Here are the key conversions:
While less common in everyday conversation, the decimeter is often used in specific fields, such as woodworking and shoemaking, for measurements that are too large for centimeters but too small for fractions of a meter.
The name "decimeter" comes from the Latin word decimus, meaning "tenth."
The prefix "deci-" always signifies one-tenth (1/10 or 10-1) of a base unit.
Understanding this prefix makes it easy to convert between different metric units.
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.
