The Angle of Impact Calculator helps determine the angle at which a droplet impacts a surface, based on its width and splatter length. In the Basic Calculator, enter values for Width of Droplet (mm) and Length of Splatter (mm) to calculate the Angle of Impact (degrees). Alternatively, you can leave one field blank to calculate the missing value.

For more precise calculations with multiple measurements, switch to the Advanced Calculator. Enter Width and Length values for two droplets, and the calculator will provide the Average Angle of Impact (degrees). Click Calculate to see results or Reset to clear all fields.

### Input Field Purpose

Input Field |
Purpose |

Width of Droplet (mm) |
Enter the width of the droplet to calculate the angle of impact. |

Length of Splatter (mm) |
Specify the length of the splatter to determine the angle of impact. |

Angle of Impact (degrees) |
Displays the calculated angle of impact based on width and length. Leave blank for auto-calculation. |

Width of Droplet 1 (mm) |
Input the width of the first droplet for the average angle calculation. |

Length of Splatter 1 (mm) |
Enter the splatter length for the first droplet. |

Width of Droplet 2 (mm) |
Input the width of the second droplet for the average angle calculation. |

Length of Splatter 2 (mm) |
Enter the splatter length for the second droplet. |

Average Angle of Impact (degrees) |
Displays the average calculated angle of impact for both droplets. |

### How To Calculate

**Example 1 – Basic Calculation**

Step |
Calculation Process |

Step 1 |
Enter **Width of Droplet (mm)** as 5 and **Length of Splatter (mm)** as 10. |

Step 2 |
Leave **Angle of Impact (degrees)** blank. |

**Result** |
The calculator displays **Angle of Impact (degrees)** as approximately 30 degrees. |

**Example 2 – Advanced Calculation**

Step |
Calculation Process |

Step 1 |
Enter **Width of Droplet 1 (mm)** as 5 and **Length of Splatter 1 (mm)** as 10. |

Step 2 |
Enter **Width of Droplet 2 (mm)** as 6 and **Length of Splatter 2 (mm)** as 12. |

**Result** |
The calculator shows the **Average Angle of Impact (degrees)** for the two measurements. |
