Mach to Kilometers per Second Converter

Convert speed from Mach to Kilometers per Second. Mach is the speed of sound in a particular medium at a specific temperature and pressure, while Kilometers per Second is a linear speed unit.

Input Parameters

Mach is the ratio of the object's speed to the speed of sound in the medium through which it's traveling.

Altitude affects the speed of sound, which in turn affects the conversion. Enter if you want more accurate results.

Calculation Results

Calculation Formula

1 Mach = 1234.8 km/h ≈ 1111.2 km/s

Where:
Mach = Speed in Mach units
km/s = Result in Kilometers per Second

The speed in Kilometers per Second equivalent to the input Mach value.

Learn how to use the Mach to Kilometers per Second Converter calculator and its working principles

How to Use the Calculator

  1. Enter the Mach value in the first input field. Mach is a dimensionless quantity representing the ratio of an object's speed to the speed of sound in the medium through which it's traveling.
  2. If you want more accurate results, optionally enter the altitude in meters. The speed of sound varies with altitude, affecting the conversion accuracy.
  3. Click the "Calculate" button to convert the Mach value to Kilometers per Second.
  4. The result will be displayed in the result field, showing the equivalent speed in Kilometers per Second.
  5. Click "Reset" to clear all input fields and start over.

Understanding Mach

Mach is a dimensionless quantity representing the ratio of an object's speed to the speed of sound in the medium through which it's traveling. For example, Mach 1 is the speed of sound, Mach 2 is twice the speed of sound, and so on.

The speed of sound varies with temperature and pressure, which in turn affects the Mach number. This calculator uses a simplified model that adjusts the speed of sound based on altitude, providing more accurate conversions than using a fixed conversion factor.

Conversion Formula

The conversion from Mach to Kilometers per Second is calculated as:

Kilometers per Second = Mach × Speed of Sound (m/s) / 1000

Practical Applications

This calculator is useful for aerospace engineers, physicists, and anyone working with high-speed aircraft or projectiles. It can help convert aircraft speed ratings from Mach to more commonly used metric units.
