## What is the Formula to convert Mach (SI standard) to Velocity of Light (in vacuum)?

The formula to convert given speed from Mach (SI standard) to Velocity of Light (in vacuum) is:

Speed_{(Velocity of Light (in vacuum))} = Speed_{(Mach (SI standard))} × 3.335640951e-9 / 0.0033892974

Substitute the given value of speed in mach (si standard), i.e., Speed_{(Mach (SI standard))} in the above formula and simplify the right-hand side value. The resulting value is the speed in velocity of light (in vacuum), i.e., Speed_{(Velocity of Light (in vacuum))}.

## Calculation

## Examples

### A fighter jet flies at Mach 2.

Convert this speed from Mach to Velocity of Light (in vacuum).

#### Answer:

**Given:**

The speed in mach (si standard) is:

Speed_{(Mach (SI standard))} = 2

**Formula:**

The formula to convert speed from mach (si standard) to velocity of light (in vacuum) is:

Speed_{(Velocity of Light (in vacuum))} = Speed_{(Mach (SI standard))} × 3.335640951e-9 / 0.0033892974

**Substitution:**

Substitute given weight **Speed _{(Mach (SI standard))} = 2** in the above formula.

Speed_{(Velocity of Light (in vacuum))} = 2 × 3.335640951e-9 / 0.0033892974

Speed_{(Velocity of Light (in vacuum))} = 0.00000196834

**Final Answer:**

Therefore, **2 mach** is equal to **0.00000196834 **.

The speed is **0.00000196834 **, in velocity of light (in vacuum).

### A supersonic aircraft reaches Mach 1.5 during flight.

Convert this speed from Mach to Velocity of Light (in vacuum).

#### Answer:

**Given:**

The speed in mach (si standard) is:

Speed_{(Mach (SI standard))} = 1.5

**Formula:**

The formula to convert speed from mach (si standard) to velocity of light (in vacuum) is:

Speed_{(Velocity of Light (in vacuum))} = Speed_{(Mach (SI standard))} × 3.335640951e-9 / 0.0033892974

**Substitution:**

Substitute given weight **Speed _{(Mach (SI standard))} = 1.5** in the above formula.

Speed_{(Velocity of Light (in vacuum))} = 1.5 × 3.335640951e-9 / 0.0033892974

Speed_{(Velocity of Light (in vacuum))} = 0.00000147625

**Final Answer:**

Therefore, **1.5 mach** is equal to **0.00000147625 **.

The speed is **0.00000147625 **, in velocity of light (in vacuum).

## Mach (SI standard)

The Mach number (Mach) is a dimensionless unit used to express the speed of an object relative to the speed of sound in the surrounding medium. A Mach number of 1 indicates the speed of sound, with higher numbers representing supersonic or even hypersonic speeds. This unit is critical in aerodynamics and aerospace engineering.

## Velocity of Light (in vacuum)

The velocity of light (c) is a constant that represents the speed at which light travels in a vacuum, approximately 299,792,458 meters per second. It is a fundamental constant in physics and is used in various equations, such as Einstein's theory of relativity. This speed is the upper limit for the speed at which information or matter can travel.
