Miles and Kilometers?
Centimeters and Inches?
Meters and Feet?
For measuring distance, meter is used. For measuring mass, kilogram is used. For estimating time, second is used.
There are different units for measuring different attributes.
A ruler
volts
It is the length of the diameter multiplied by itself, with the units being the square of the units used for measuring the diameter.
metre
For measuring length/distance, meter is used. Other units are km / cm/ mm.
For measuring distance, meter is used. For measuring mass, kilogram is used. For estimating time, second is used.
There are two main units of distance used for measuring space distances, they are solar units and light years
I think those are miles, feet, inches, yards (measuring distance) and pounds, ounces, gallons (measuring weight). For temperature it is Fahrenheit (used only by Americans and Belize)
Acres are used for measuring area, while kilometers are used for measuring distance. These two units can't be converted between one to another.
In olden days, they were used for measuring mass, distance and volumes. Nowadays, these units are not used in science anywhere in the world except in the US.
speed =distance/speed .units to express speed are m/s and km/hr.
Three units are commonly used in astronomy - the astronomical unit; the light-year; and the parsec.
I don't mean anything because I never used the term "units of measuring weight."
Meters; for larger distances or sizes, kilometers. In astronomy, the following non-SI units are often used: astronomical units; light-years; parsecs.
The unit of measurement that would be best for measuring the distance from the North Pole to the equator is kilometers (km) or nautical miles (nmi). These units are commonly used to measure long distances and are suitable for measuring the Earth's surface.
