Coriolis Force Magnitude Calculator
Coriolis Force Magnitude Calculator computes the magnitude of the Coriolis force acting on a moving object in a rotating frame, such as Earth. Input the mass, velocity, angular velocity of the frame, latitude, select units, and calculate the force.

How to Use Coriolis Force Magnitude Calculator:
- Enter the mass (m), velocity (v), angular velocity of the rotating frame (Ω, default is Earth’s 7.292×10⁻⁵ rad/s), and latitude (θ) using the keypad or direct input; use “Next” to switch fields.
- Select appropriate units for mass (kg, g) and velocity (m/s, mm/s, mph). Angular velocity and latitude use rad/s and degrees, respectively.
- Click “Calculate” to see step-by-step results for the Coriolis force magnitude.
- Use “Share Result” to get shareable text or “Copy Result” to copy to clipboard.
Formula:
Coriolis Force Magnitude (F):
F = 2 × m × v × Ω × sin(θ)
Where: F = Coriolis force magnitude (N), m = mass (kg), v = velocity (m/s), Ω = angular velocity of the rotating frame (rad/s), θ = latitude (degrees)
Important Notes:
- Inputs for mass and velocity magnitude must be positive. Angular velocity and latitude can be positive or negative. Zero angular velocity or velocity will result in zero force.
- The calculator assumes the velocity is perpendicular to the rotation axis for maximum effect; actual Coriolis force depends on the direction of motion.
- Earth’s angular velocity (7.292×10⁻⁵ rad/s) is pre-filled for convenience but can be modified for other rotating frames.
- Latitude (θ) is converted to radians internally for the sin(θ) calculation.
