## How to Convert Feet Per Second to Kilometers Per Second

To convert a foot per second measurement to a kilometer per second measurement, multiply the speed by the conversion ratio. One foot per second is equal to 0.000305 kilometers per second, so use this simple formula to convert:

The speed in kilometers per second is equal to the feet per second multiplied by 0.000305.

**For example,**here's how to convert 5 feet per second to kilometers per second using the formula above.

Feet per second and kilometers per second are both units used to measure speed. Keep reading to learn more about each unit of measure.

## Feet Per Second

Feet per second are a measurement of speed expressing the distance travelled in feet in one second.

The foot per second is a US customary and imperial unit of speed. Feet per second can be abbreviated as *ft/s*, and are also sometimes abbreviated as *ft/sec* or *fps*. For example, 1 foot per second can be written as 1 ft/s, 1 ft/sec, or 1 fps.

Feet per second can be expressed using the formula:

v_{ft/s} = d_{ft}t_{sec}

The velocity in feet per second is equal to the distance in feet divided by time in seconds.

## Kilometers Per Second

Kilometers per second are a measurement of speed expressing the distance travelled in kilometers in one second.

The kilometer per second, or kilometre per second, is an SI unit of speed in the metric system. Kilometers per second can be abbreviated as *km/s*, and are also sometimes abbreviated as *km/sec*. For example, 1 kilometer per second can be written as 1 km/s or 1 km/sec.

Kilometers per second can be expressed using the formula:

v_{km/s} = d_{km}t_{sec}

The velocity in kilometers per second is equal to the distance in kilometers divided by time in seconds.

## Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

## Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

### Here is a list of some of the common metric prefixes:

- “kilo” – 1,000x larger
- “hecto” – 100x larger
- “deca” – 10x larger
- “deci” – 10x smaller
- “centi” – 100x smaller
- “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”

The u in Until refers to the base unit.
