What is a Convert Degrees to Meters Calculator?
A convert degrees to meters calculator is a tool that transforms an angular measurement (degrees) into a linear distance (meters). This conversion is not straightforward because a degree’s length in meters changes depending on its location on Earth. For latitude, the distance is relatively constant, but for longitude, it varies significantly with latitude, becoming smaller as one moves from the equator to the poles. This calculator helps in accurately determining this distance, which is crucial for applications in geography, navigation, and spatial analysis.
Convert Degrees to Meters Formula and Explanation
The formula to convert degrees to meters depends on whether you are converting latitude or longitude.
For Latitude:
The distance of one degree of latitude is relatively constant. A common approximation is:
Distance (m) = Degrees × 111,132.95
For Longitude:
The distance of one degree of longitude depends on the latitude. The formula is:
Distance (m) = Degrees × 111,320 × cos(latitude)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Degrees | The angular distance to be converted. | Degrees (°) | 0-360 for longitude, 0-90 for latitude |
| Latitude | The position on Earth north or south of the equator. | Degrees (°) | -90 to 90 |
| Distance | The resulting linear distance. | Meters (m) | Varies |
Practical Examples
Example 1: Converting Latitude to Meters
If you want to convert 2 degrees of latitude to meters:
- Input Degrees: 2°
- Conversion Type: Latitude
- Result: 2 × 111,132.95 = 222,265.9 meters
Example 2: Converting Longitude to Meters at a Specific Latitude
If you want to convert 1 degree of longitude at a latitude of 45°:
- Input Degrees: 1°
- Conversion Type: Longitude
- Latitude: 45°
- Result: 1 × 111,320 × cos(45°) = 78,715.6 meters
How to Use This Convert Degrees to Meters Calculator
- Enter the number of degrees you wish to convert in the “Degrees (°)” field.

Key Factors That Affect Convert Degrees to Meters
- Location on Earth: The Earth is not a perfect sphere, so the length of a degree can vary slightly.
- Latitude: This is the most critical factor for longitude conversions; a degree of longitude at the equator is much longer than near the poles.
- Altitude: At higher altitudes, the Earth’s radius is effectively larger, which will slightly increase the distance.
- The Model of the Earth Used: Different geodetic models (e.g., WGS84, GRS80) have slightly different parameters for the Earth’s shape, leading to small variations in conversion factors.
- Measurement Accuracy: The precision of the input degrees and latitude will affect the accuracy of the result.
- Local Topography: The formulas assume a smooth surface, but mountains and valleys will affect the actual ground distance.
FAQ
- Why does the length of a degree of longitude change?
- The lines of longitude converge at the poles. As you move away from the equator, the distance between them decreases, reaching zero at the poles.
- Is the length of a degree of latitude always the same?
- It’s nearly the same, but because the Earth is an oblate spheroid (slightly flattened at the poles), there’s a small variation. A degree of latitude is slightly longer at the poles than at the equator.
- What is the most accurate way to convert degrees to meters?
- For the highest accuracy, you should use geodetic formulas that account for the Earth’s elliptical shape, such as Vincenty’s formulae.
- Can I use this calculator for any planet?
- No, this calculator is specifically designed for Earth, using its radius and shape in the calculations.
- What are degrees, minutes, and seconds?
- These are subunits of a degree. One degree is equal to 60 minutes, and one minute is equal to 60 seconds.
- How does this relate to GPS coordinates?
- GPS coordinates are given in latitude and longitude. This calculator can help you determine the real-world distance between two GPS points that differ by a certain number of degrees.
- What is a nautical mile?
- A nautical mile is a unit of distance used in marine and aviation navigation. It is approximately equal to one minute of latitude.
- What if I need to convert meters back to degrees?
- You can use the inverse of the formulas. For latitude, you would divide the meters by 111,132.95. For longitude, you would divide the meters by (111,320 * cos(latitude)).
