spherical latitude band surface area calculator online

Use spherical latitude band surface area online for south latitude deg, north latitude deg, radius km. Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.

How to use it

Enter south latitude deg. Set north latitude deg, radius km. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
south latitude degMain input. Signed finite values. Maximum 90.30
north latitude degOption. Signed finite values. Maximum 90.40
radius kmOption. Positive values. 6371.0088

Calculation method

area_km2 = 2*pi*radius_km^2*positive(sind(north_latitude_deg)-sind(south_latitude_deg)) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply spherical latitude band surface area to the case below, keeping the displayed units and assumptions. Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.

Spherical Latitude Band Surface Area — worked case

Settings: north latitude deg: 40; radius km: 6371.0088

Input:

30

Calculated result for these inputs:

Output:

{
  "area_km2": 36415543.963387616
}

Choose the right tool

Choose great-circle tools for shortest spherical paths and rhumb tools for constant bearings. Spherical models differ from ellipsoidal survey calculations. Web-map tiles have latitude limits and grid bearings require a stated convergence convention.

Limitations and common mistakes

  • Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
