# How to Convert 9mm Bullet Speed from Miles per Hour to Meters per Second

When dealing with units of measurement, it's essential to convert between different scales to ensure accuracy. In this case, we are converting the speed of a 9mm bullet from miles per hour to meters per second.

## Conversion Factors:

1 mile = 1.60934 kilometers

1 kilometer = 0.621371 miles

1 hour = 3600 seconds

## Dimensional Analysis:

First, we convert miles to kilometers by multiplying the speed of the bullet in miles per hour by 1.60934 km/mi. This step gives us the speed of the bullet in kilometers per hour.

Next, we convert kilometers per hour to meters per second by multiplying the speed in kilometers per hour by 0.277778 m/s/km. This final step gives us the speed of the bullet in meters per second.

## Calculation:

Let's calculate the speed of a 9mm bullet that travels at 853 miles per hour in meters per second:

853 mph * 1.60934 km/mi * 0.277778 m/s/km = 385.698 m/s

**Final Answer:**

The speed of a 9mm bullet traveling at 853 miles per hour is equivalent to 385.698 meters per second.
