How to Use the Crosswind Calculator
This tool calculates the crosswind component—the part of the wind that pushes you sideways relative to your heading. Follow these steps:
- Enter Wind Speed – Type the wind speed (e.g., 20). Must be a positive number.
- Enter Wind Direction – Input the wind direction in degrees (0–360, e.g., 270).
- Enter Your Heading – Your aircraft or vehicle heading in degrees (0–360, e.g., 360).
- Select Unit – Choose from Knots, Miles per Hour, or Kilometers per Hour.
- Click "Calculate" – The crosswind component appears below, along with the angle difference.
What the result means: The crosswind value shows how much wind is coming from the side. Use it for landing, sailing, or any directional planning. The formula used is: Crosswind = Wind Speed × sin(angle difference).
All inputs must be valid numbers. Directions and headings are in degrees (0–360).

Frequently Asked Questions
Crosswind is the component of wind that blows perpendicular to your direction of travel, affecting stability and control.
Crosswind = Wind Speed × sin(Angle Difference), where angle difference is the absolute difference between wind direction and your heading.
Knots, miles per hour (mph), and kilometers per hour (km/h).
