## How to convert

1 inch per second (in/s) = 300 foot per hour (ft/h). Inch Per Second (in/s) is a unit of Speed used in Standard system. Foot Per Hour (ft/h) is a unit of Speed used in Standard system.

## Inches per second: A unit of speed

Inches per second ( in/s) is a unit of speed or velocity in the US customary and imperial systems. It measures how fast an object is moving by calculating the distance traveled in inches divided by the time taken in seconds. For example, if a worm travels 2 inches in 1 second, its speed is 2 in/s.

## How to convert inches per second

Inches per second can be converted to other units of speed or velocity by using simple conversion factors. Here are some common units and their conversion factors:

• Meters per second (m/s): To convert from in/s to m/s, multiply by 0.0254. To convert from m/s to in/s, divide by 0.0254. For example, 1 in/s is equal to 0.0254 m/s, and 10 m/s is equal to 393.701 in/s.

## Where inches per second are used

Inches per second are mainly used in engineering and manufacturing to measure the speed or velocity of machines and processes.

For example, the cutting speed of a lathe or a milling machine is often given in inches per minute, which is equivalent to inches per second divided by 60.

The rotational speed of a hard disk drive is often given in revolutions per minute, which can be converted to inches per second by multiplying by the circumference of the disk.

The flow rate of a fluid through a pipe or a nozzle is often given in gallons per minute, which can be converted to inches per second by multiplying by the cross-sectional area of the pipe or the nozzle.

## Definition of inches per second

According to the US customary and imperial systems definition, one inch per second is the speed of a body that covers a distance of one inch in a time of one second.

Mathematically, it can be expressed as:

where v is the speed or velocity in inches per second, s is the distance traveled in inches, and t is the time taken in seconds.

## History of inches per second

The concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc.

The inch was originally derived from the Roman uncia which was one twelfth of a Roman foot or about 0.97 inches .

The second was originally defined in terms of the Earth’s rotation as one eighty-six thousand four hundredth of a mean solar day.

The combination of these two units resulted in the inch per second as a unit of speed or velocity.

The inch per second was officially adopted as part of the US customary and imperial systems in the late 18th century.

Inch per second also can be marked as ips.

## Definition of Feet Per Hour

Feet per hour (f/h) is a unit of speed that measures how fast something is moving in terms of feet per unit of time. It is a US Standard unit that is derived from the base unit of length, the foot, and the base unit of time, the hour. It is rarely used however, as the units of feet per second and miles per hour are considered sufficient for most situations.

One foot per hour is equal to 0.000084666666666667 meters per second, or 0.0003048 kilometers per hour. It can also be converted to other units of speed, such as miles per hour, knots, or meters per second, by using appropriate conversion factors.

## How to Convert Feet Per Hour

To convert feet per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert feet per hour to miles per hour, we need to multiply by 0.0001893939394, since there are 0.0001893939394 miles in one foot. To convert feet per hour to meters per second, we need to multiply by 0.000084666666666667, since there are 0.000084666666666667 meters in one foot.

Here are some examples of how to convert feet per hour to other units of length in the US Standard system and the SI system:

• To convert 10 f/h to miles per hour (mph), we multiply by 0.0001893939394: 10 f/h x 0.0001893939394 = 0.001893939394 mph
• To convert 20 f/h to feet per second (fps), we divide by 3600, since there are 3600 seconds in one hour: 20 f/h / 3600 = 0.005555555556 fps
• To convert 30 f/h to knots (kn), we multiply by 0.0001645788337, since there are 0.0001645788337 nautical miles in one foot: 30 f/h x 0.0001645788337 = 0.004937365011 kn
• To convert 40 f/h to meters per second (m/s), we multiply by 0.000084666666666667: 40 f/h x 0.000084666666666667 = 0.003386666667 m/s
• To convert 50 f/h to meters per minute (m/min), we multiply by 0.00508, since there are 0.00508 meters in one foot: 50 f/h x 0.00508 = 0.254 m/min
• To convert 60 f/h to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and multiply by 0.000084666666666667: 60 f/h x 100 x 0.000084666666666667 = 0.508 cm/s

## Where Feet Per Hour Are Used

Feet per hour are mainly used for measuring very slow speeds or velocities of objects or phenomena that move in terms of feet per unit of time. They are often used in scientific fields such as geology, biology, astronomy, and physics, where the speed or velocity of an object or phenomenon is very small compared to the usual units of speed.

For example, a glacier may have a speed of a few feet per hour, which means that it moves a few feet in one hour. A snail may have a speed of up to 47 feet per hour, which means that it can travel up to 47 feet in one hour.1 A planet may have an orbital velocity of thousands of feet per hour, which means that it covers thousands of feet along its orbit in one hour.

Feet per hour are also used in some other fields where the speed or velocity of an object or phenomenon is measured in terms of feet per unit of time.

## History of Feet Per Hour

The origin of feet per hour as a unit of speed can be traced back to the development of the US Standard system and the foot as a unit of length in the late eighteenth century. The foot was defined as one third of a yard based on the English standard foot.

The term foot first appeared in English in the late fourteenth century, but it was not until later in the early nineteenth century that the use of feet per hour became more common; before that, other units such as inches per hour or yards per hour were preferred for expressing speed.

Feet per hour have been used ever since as a standard unit of speed for measuring very slow speeds or velocities of objects or phenomena that move in terms of feet per unit of time. They have also been adopted by some international organizations and conventions, such as the International System of Units and the International Astronomical Union.

• To convert 700 f/h to millimeters per minute, we multiply by 1000, since there are 1000 millimeters in one meter, and multiply by 0.00508: 700 f/h x 1000 x 0.00508 = 3556 mm/min
Foot per hour also can be marked as foot/hour.
