Online tool for converting geodetic latitude to geocentric latitude, supporting the conversion between geodetic latitude and geocentric latitude. This tool supports latitude batch conversion, with latitude units supporting degrees, radians, and degrees, and supports selecting or customizing ellipsoid parameters. The conversion result can be downloaded locally.
Online tool for converting between geodetic latitude and geocentric latitude, supporting the conversion of geodetic latitude to geocentric latitude and geocentric latitude to geodetic latitude. Latitude units support degrees, radians, and hundredths.
- Input Latitudes : Input floating-point number latitude, one latitude per line, supports multiple lines of input.
- Convert Type : Select the convert type as geodetic latitude to geocentric latitude, or geocentric latitude to geodetic latitude.
- Ellipsoid : Select the ellipsoid definition, which supports user-defined ellipsoids.
- a : The semi-major axis of a custom ellipsoid, in meters (m). The value range is [6370000,6379999].
- rf : Reverse flattening of the ellipsoid, 1/f. The value range is [270,300].
- Unit : Input latitude and output latitude units, supporting degree, radian, and grad.
- Precision : The number of digits retained after the decimal point, ranging from 0 to 10.
- Open File : Support for opening UTF-8 encoded text files.
- Download : Download the conversion result as a UTF-8 encoded file.
