Unit Explanations
Kilometer per Secondkm/s
Source UnitThe kilometer per second (km/s) is a non-SI unit of speed that quantifies the distance traveled in kilometers over a duration of one second. It is commonly used in astrophysics, aeronautics, and various scientific fields to express high-velocity scenarios. A speed of 1 km/s indicates that an object can cover a distance of 1 kilometer in the time span of 1 second. This unit is particularly useful in contexts where both vast distances and time intervals are significant, such as in space exploration and satellite movements.
Current Use
The kilometer per second is predominantly used in scientific fields such as astrophysics and aerospace engineering. It is particularly relevant when discussing the velocities of objects in space, such as spacecraft or astronomical phenomena. For instance, the speed of light is often expressed in kilometers per second, making it easier to relate to other distances in space. Various scientific studies and research papers utilize the km/s unit for reporting findings related to speed.
Fun Fact
The speed of light is approximately 299,792 km/s, making it the fastest known speed in the universe.
Yard Houryd/h
Target UnitThe yard hour is a unit of speed that quantifies the distance of one yard covered in one hour. It is a non-SI unit often used in specific fields, such as sports and leisure activities where yards are a common measurement unit. To express this speed in more familiar SI terms, it can be converted into meters per second (m/s) or kilometers per hour (km/h). Mathematically, it can be defined as 1 yd/h = 0.000254 m/s, indicating a very slow rate of speed, typically used in contexts where precise measurements are not critical.
Current Use
Despite the prevalence of metric units, the yard hour is still used in various contexts, especially in the United States where yards are common in everyday language. In sports, particularly in American football and track events, the yard hour may be referenced when discussing player speeds, field distances, or race times. Additionally, it can be applied in gardening or landscaping projects where yard distances are common, and speed in completing tasks is measured.
Fun Fact
The yard hour is approximately equivalent to 0.000254 meters per second, emphasizing its slow pace.

Kilometer per Second
speed • Non-SI
Definition
The kilometer per second (km/s) is a non-SI unit of speed that quantifies the distance traveled in kilometers over a duration of one second. It is commonly used in astrophysics, aeronautics, and various scientific fields to express high-velocity scenarios. A speed of 1 km/s indicates that an object can cover a distance of 1 kilometer in the time span of 1 second. This unit is particularly useful in contexts where both vast distances and time intervals are significant, such as in space exploration and satellite movements.
History & Origin
The kilometer per second originated from the metric system, which was developed in France during the late 18th century. The metric system standardized measurements based on decimal units, allowing for ease of conversion and calculation. The kilometer itself is defined as 1,000 meters, a unit based on the meter, which was originally defined by the distance between the North Pole and the equator. The concept of measuring speed as distance over time emerged from the need to quantify movement in various scientific disciplines.
Etymology: The term 'kilometer' is derived from the Greek word 'chilioi,' meaning 'thousand,' and the French word 'mètre,' meaning 'measure.' Therefore, a kilometer literally means 'one thousand meters.'

Yard Hour
speed • Non-SI
Definition
The yard hour is a unit of speed that quantifies the distance of one yard covered in one hour. It is a non-SI unit often used in specific fields, such as sports and leisure activities where yards are a common measurement unit. To express this speed in more familiar SI terms, it can be converted into meters per second (m/s) or kilometers per hour (km/h). Mathematically, it can be defined as 1 yd/h = 0.000254 m/s, indicating a very slow rate of speed, typically used in contexts where precise measurements are not critical.
History & Origin
The yard as a unit of measurement has ancient origins, tracing back to the Anglo-Saxon period in England, where it was used as a standard length measure. The term 'yard' is believed to be derived from the Old English word 'gyrd,' which means a stick or rod. The yard was standardized in the 13th century during the reign of King Edward I of England. The concept of measuring speed in terms of yards per hour emerged as a practical way to reference movement, especially in activities like horse racing and hunting, where distances were frequently described in yards.
Etymology: The word 'yard' is derived from the Old English 'gyrd' and has roots in Latin and Germanic languages, indicating a length or measure.
Current Use
Despite the prevalence of metric units, the yard hour is still used in various contexts, especially in the United States where yards are common in everyday language. In sports, particularly in American football and track events, the yard hour may be referenced when discussing player speeds, field distances, or race times. Additionally, it can be applied in gardening or landscaping projects where yard distances are common, and speed in completing tasks is measured.
💡 Fun Facts
- •The yard hour is approximately equivalent to 0.000254 meters per second, emphasizing its slow pace.
- •Yards are commonly used in American sports, especially football, where field lengths are measured in yards.
- •The yard was historically used as a standard measure for fabric, with one yard being the length of a man's belt.
