 # Fps to Mph Calculator (Speed)

When you calculate speed, do you use miles per hour or feet per second? It depends on the distance you're traveling, but there will likely be a time when you'll have to switch between the two.

If you are wondering how many fps in one mph, it's 1.4666667. Luckily, you can use also our easy fps to mph calculator to get quick and effortless conversions between 30 speed and velocity units.

To learn all about these units and how to convert them using an equation, check out the guide below. If you find it useful, please share it with your friends.

## What is feet per second?

Fps is a unit of both speed and velocity. It expresses the distance you travel in feet. With this unit of measurement, time is expressed in seconds.

How often will you use fps? Well, you'll be surprised.

Since feet don't cover a lot of distance compared to miles, many people don't use this unit of measurement as much. But we're always on the go, whether we're walking or driving. So fps can have a lot of value in our lives.

Our body's sensory of motion responds to fps. When we travel and our inner-ear senses detect forward motion, our body recognizes fps. This is the reason why we measure fps by time, not just distance.

### Examples

Say you're in a car and count one second, you could easily gain 100 feet distance when you're driving about 70 miles/hour. But, the distance is just as complex if you count one second while traveling by foot.

If you're running, you can gain 32 feet in distance after a second. While walking, you can gain about 3 feet in a second.

## What is miles per hour?

Mph is the unit of speed that most Americans know. Its how we determine our vehicle speed and distance.

Miles per hour measures our momentum by estimating how many miles we cover in an hour. The measurement starts with one mile and estimates how many more miles you'll cover.

The higher the number, the faster you'll go and the more miles you'll cover in an hour. The lower the number, the slower you'll go and the less distance (miles) you'll cover.

These numbers assume you're going faster or slower and measures the distance you travel in an hour based on your pace.

### Examples

All American vehicles use mph. Most Americans use this measurement while driving their car. But you can also use it when driving a motorcycle, bicycle, or when riding in a train.

Here are common mph uses:

• Speed limits
• Monitor vehicle speed
• Gauge ball acceleration in sporting events, such as tennis and baseball

### History

Mph as a speed measurement dates back to the 18th century. It was originally used to determine the agility of motor coaches. The trend continued when trains became the main transportation method.

Faster measurement units were required, and miles per hour was the easiest to translate.

## Why convert feet per second and miles per hour?

Now you know a briefing of the measurements, we can focus on the conversion. But why should we? For one of two reasons:

• You want to convert distance to speed
• You want to convert speed to distance

Here are common reasons why you'll want to convert these measurements:

### Fps to Mph

Let's say you're riding your bike and are unsure of how fast you're going. But you're able to measure your distance and estimate each second you rode your bike. This can give you a better understanding of your bike pace.

#### Example

You measured your bike acceleration over 30 seconds. Your Apple Watch estimates that you covered 660 feet, which means your speed was 22 feet per second (660 / 30 = 22).

Plug that into the conversion calculator and you'll know that you reached a pace of 15 miles/hour.

### Mph to Fps

Let's say you're training for a race. You're measuring your agility in miles or kilometers, but you want to optimize your performance. You're training for a 5k, which is about three miles.

After estimating an average running pace of 6.22 miles/hour, you want to know how many feet you are covering in a second. You use the conversion calculator and get the number 9.12 fps.

Fun fact, top sprinter Usain Bolt can achieve speeds of 34.25 fps.

## How do you convert fps and mph?

You can easily convert measurements by using the conversion tool or by calculating it yourself. Below, we will go over the conversion rate between ft/s, mi/h, and km/h.

### Feet per second to miles per hour

One foot per second = 0.681818 miles per hour.

#### Example

Let's say your distance is five feet. You can find your total by using this equation:

5 ft/second = (5 x 0.681818)

= 3.4 mi/hour.

### Feet/second to kilometers per hour

One foot per second = 1.09728 kilometers per hour

#### Example

For a distance of five feet, you'll use the following equation:

5 ft/sec = (5 x 1.09728)

= 5.4864 km/hour

### Miles per hour to feet per second

One mile per hour = 1.4666667 ft per second

#### Example

If your distance is fifty miles, find your total using the following equation:

50 miles per hour = (50 x 1.4666667)

= 73.3333333 ft/second

### Miles/hour to kilometers per hour

One mile per hour = 1.609344 kilometer per hour

#### Example

We'll assume a distance of sixty miles. You can convert using the following equation:

60 miles/hour = (60 x 1.609344)

= 96.56064 km/hour

## Why use a conversion calculator?

This equation to convert isn't difficult. But why should we use a conversion rate calculator? There are two main reasons:
