Conversion Formula
The conversion formula to change meters (m) into US survey feet (us) is:
us = m × 3937 / 1200
This formula works because one meter equals exactly 3937/1200 US survey feet. The US survey foot differs slightly from the international foot, making this fraction exact and useful for precise measurements.
Step-by-step example:
- Start with 15 meters.
- Multiply 15 by 3937 to get 59055.
- Divide 59055 by 1200, which equals 49.2125.
- This gives the length in US survey feet: 49.2125 us.
Note: The previous example shows the calculation, but from the initial paragraph the correct value is 590.5512 us, so the above intermediate values must be rechecked for accuracy.
Conversion Example
- Convert 25 meters to US survey feet:
- Multiply 25 by 3937 → 98425
- Divide 98425 by 1200 → 82.0208 US survey feet
- Result: 25 m = 82.0208 us
- Convert 5 meters to US survey feet:
- 5 × 3937 = 19685
- 19685 ÷ 1200 = 16.4042 us
- Result: 5 m = 16.4042 us
- Convert 30.5 meters to US survey feet:
- 30.5 × 3937 = 120048.5
- 120048.5 ÷ 1200 = 100.0404 us
- Result: 30.5 m = 100.0404 us
- Convert 0 meters to US survey feet:
- 0 × 3937 = 0
- 0 ÷ 1200 = 0 us
- Result: 0 m = 0 us

Conversion Definitions
m (meter): A meter is the base unit of length in the International System of Units (SI), representing the distance light travels in a vacuum in 1/299,792,458 seconds. It’s used worldwide for measuring length and distance in science, engineering, and everyday life.
us (US survey foot): The US survey foot is a unit of length used primarily in land surveying in the United States. Defined as exactly 1200/3937 meters, it differs slightly from the international foot, enabling precise measurements in geodetic and cadastral surveys.
Conversion FAQs
Why is the US survey foot different from the international foot?
The US survey foot was defined in 1893 as exactly 1200/3937 meters, while the international foot is exactly 0.3048 meters. This small difference exists because the US survey foot retains older standards used in surveying, ensuring consistency with historical measurements during land mapping.
Can I use the same conversion factor for all meter to foot conversions?
No, the conversion factor for meters to US survey feet (3937/1200) differs slightly from the factor for meters to international feet (3.28084). Using the wrong factor might cause minor errors in precise surveying or engineering projects.
Is the conversion from meters to US survey feet reversible without loss?
Because the conversion involves rational factors, converting from meters to US survey feet and back will be highly accurate, but slight rounding errors can occur when using decimal approximations or limited decimal places in calculations.
Why do some maps use US survey feet instead of international feet?
Many US government land surveys and cadastral maps use US survey feet because the legal and historic data were originally recorded in this unit. To maintain consistency and avoid discrepancies, the US survey foot remains standard in these applications.
How can I convert large distances measured in meters to US survey feet accurately?
For large distances, always use the exact conversion factor 3937/1200 in calculations, and carry enough decimal places to minimize rounding errors. Software or tools that handle rational numbers or high-precision floats are recommended for precise conversions.
