The mile per hour (mph) is a unit of speed commonly used in the United States and the United Kingdom. It quantifies the distance traveled in miles over the duration of one hour. This measurement is particularly relevant in transportation and travel, where understanding speed is crucial for safety and efficiency.
The mile per hour is standardized under the imperial system, where one mile is equivalent to 1,609.34 meters. This unit is widely recognized and utilized in various contexts, including road signs, vehicle speedometers, and aviation.
The concept of measuring speed dates back to ancient civilizations, but the mile as a unit of distance has its roots in Roman times. The mile was initially defined as 1,000 paces of a Roman soldier. Over time, the mile evolved, and the mile per hour became a standard unit for measuring speed, particularly in the context of land and air travel.
To convert 100 miles per hour to kilometers per hour, you can use the following formula: [ \text{Speed in km/h} = \text{Speed in mph} \times 1.60934 ] For example: [ 100 \text{ mph} \times 1.60934 = 160.934 \text{ km/h} ]
Mile per hour is predominantly used in the United States for speed limits on roads and highways. It is also employed in various sports and activities, such as running and cycling, to gauge performance and speed.

The Astronomical Unit per Day (AU/d) is a unit of measurement used to express velocity in terms of the distance traveled in astronomical units over the course of a day. One astronomical unit (AU) is defined as the average distance from the Earth to the Sun, approximately 149.6 million kilometers. This tool allows users to convert and calculate velocities in AU/d, making it essential for astronomers, astrophysicists, and space enthusiasts.
The AU/d is standardized within the scientific community, primarily used in fields related to astronomy and space exploration. The unit provides a consistent framework for measuring vast distances in space, allowing for easier comparisons and calculations across various celestial phenomena.
The concept of the astronomical unit dates back to the early studies of the solar system. It was first used in the 17th century when astronomers sought to quantify the distances between celestial bodies. Over time, the AU has evolved, with its definition being refined as measurement techniques improved. The AU/d emerged as a practical unit for expressing velocities in the context of space travel and celestial mechanics.
To illustrate how to use the AU/d tool, consider a spacecraft traveling at a speed of 0.1 AU per day. This means that the spacecraft covers 0.1 times the average distance from the Earth to the Sun each day. If you want to convert this to kilometers, simply multiply 0.1 by the average distance of 149.6 million kilometers, resulting in a speed of approximately 14.96 million kilometers per day.
The AU/d unit is particularly useful for:
