## What is the Formula to convert Kilometer/second to Velocity of Light (in vacuum)?

The formula to convert given speed from Kilometer/second to Velocity of Light (in vacuum) is:

Speed_{(Velocity of Light (in vacuum))} = Speed_{(Kilometer/second)} × 3.335640951e-9 / 0.001

Substitute the given value of speed in kilometer/second, i.e., Speed_{(Kilometer/second)} 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 spacecraft travels at a speed of 8 kilometers per second.

Convert this speed from kilometers per second to Velocity of Light (in vacuum).

#### Answer:

**Given:**

The speed in kilometer/second is:

Speed_{(Kilometer/second)} = 8

**Formula:**

The formula to convert speed from kilometer/second to velocity of light (in vacuum) is:

Speed_{(Velocity of Light (in vacuum))} = Speed_{(Kilometer/second)} × 3.335640951e-9 / 0.001

**Substitution:**

Substitute given weight **Speed _{(Kilometer/second)} = 8** in the above formula.

Speed_{(Velocity of Light (in vacuum))} = 8 × 3.335640951e-9 / 0.001

Speed_{(Velocity of Light (in vacuum))} = 0.00002668513

**Final Answer:**

Therefore, **8 km/s** is equal to **0.00002668513 **.

The speed is **0.00002668513 **, in velocity of light (in vacuum).

### A meteor enters the Earth's atmosphere at 15 kilometers per second.

Convert this speed from kilometers per second to Velocity of Light (in vacuum).

#### Answer:

**Given:**

The speed in kilometer/second is:

Speed_{(Kilometer/second)} = 15

**Formula:**

The formula to convert speed from kilometer/second to velocity of light (in vacuum) is:

Speed_{(Velocity of Light (in vacuum))} = Speed_{(Kilometer/second)} × 3.335640951e-9 / 0.001

**Substitution:**

Substitute given weight **Speed _{(Kilometer/second)} = 15** in the above formula.

Speed_{(Velocity of Light (in vacuum))} = 15 × 3.335640951e-9 / 0.001

Speed_{(Velocity of Light (in vacuum))} = 0.00005003461

**Final Answer:**

Therefore, **15 km/s** is equal to **0.00005003461 **.

The speed is **0.00005003461 **, in velocity of light (in vacuum).

## Kilometer/second

The kilometer per second (km/s) is a unit of speed that represents how many kilometers an object travels in one second. This unit is often used in astronomy and space science to describe the velocities of celestial bodies and spacecraft, as these speeds are far beyond those encountered in everyday life.

## 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.
