Elara Bennett1 chain equals approximately 20.1168 surveying units.
This means that if you convert 1 chain into surveying measurement, you get about 20.1168 units. The chain, used in land surveying, is an old measurement tool, and the surveying unit is based on feet, where 1 chain equals 66 feet. To convert, we multiply the chain value by 20.1168.
Conversion Calculation
The conversion from chains to surveying units works because 1 chain is exactly 66 feet, and the surveying unit is based on foot measurements. The precise conversion factor is derived from the relationship between these units. Specifically, 1 chain equals 66 feet, and since the survey unit is typically the foot, the conversion factor is approximately 20.1168.

Conversion Formula
The formula to convert chain to surveying units is straightforward: multiply the number of chains by 20.1168. This works because 1 chain equals 66 feet, and the surveying unit is based on feet. So, the calculation is: chains × 66 feet/chain ÷ 3.28 (feet per meter) for metric, or simply chains × 20.1168 for feet.
For example, converting 1 chain: 1 × 66 feet = 66 feet, which matches 1 × 20.1168 units, considering the unit basis. The multiplication ensures each chain is correctly scaled into the surveying measurement.
Conversion Example
- Convert 2 chains:
- Step 1: Multiply 2 by 20.1168.
- Step 2: 2 × 20.1168 = 40.2336.
- Result: 2 chains equals 40.2336 surveying units.
- Convert 0.5 chains:
- Step 1: Multiply 0.5 by 20.1168.
- Step 2: 0.5 × 20.1168 = 10.0584.
- Result: 0.5 chains equals 10.0584 surveying units.
- Convert 5 chains:
- Step 1: Multiply 5 by 20.1168.
- Step 2: 5 × 20.1168 = 100.584.
- Result: 5 chains equals 100.584 surveying units.

Conversion Definitions
Chain
A chain is an old land measurement unit used primarily in surveying, consisting of 100 links, and equal to 66 feet or 4 rods. It was historically used for measuring large plots of land and helps relate distances in surveying to standardized units.
Surveying
Surveying refers to the process of measuring and mapping land, involving the use of measurements like chains, feet, and meters. It is a fundamental activity in land development, construction, and mapping, ensuring accurate land boundaries and features are recorded.
Conversion FAQs
How do I convert 1 chain into survey units manually?
Multiply 1 by 20.1168 to get the survey measurement. So, 1 chain equals approximately 20.1168 units in survey measurements, based on the standard conversion factor that relates chains to feet, then to survey units.
Why is the conversion factor 20.1168 for chain to survey units?
This factor is derived from 66 feet per chain, divided by the feet in a survey unit, which is 3.28 feet per meter or 1 foot in the standard measurement system, resulting in 20.1168 as the precise multiplier for conversion.
Can I use this conversion for metric measurements?
Yes, but you need to modify the factor accordingly. The current conversion is for feet-based survey units. For meters, divide 66 feet by 3.28 to get meters, then convert accordingly. The tool is set for survey units based on feet.
