Why does refractive index not have units?
Refractive index is a dimensionless quantity because it is the ratio of the speed of light in a vacuum to the speed of light in a medium. Since it is a ratio of two similar quantities, it does not have any units.
What is 677 miles into hours?
You don't convert units of length to units of time; those two are utterly incompatible.If an object moves at a certain speed, you can use the formula distance = speed x time, to relate the three. If you know two of these three pieces of information, you can calculate the third.You don't convert units of length to units of time; those two are utterly incompatible.If an object moves at a certain speed, you can use the formula distance = speed x time, to relate the three.

What are the units for rotational speed?
the units for rotational speed are radians / sec or degrees / sec
How many hours in a km?
Hours are units of time. Kilometers are units of distance. The two are not related, and can not be converted without knowing something else, such as speed.
What are two units of measure for speed?
In order to measure speed, a unit for distance and a unit for time must be used. Common units with which speed is expressed are meters per second (m/s), miles per hour (mph), and kilometers per hour (km/h).
What does the SI unit for speed, m/s, stand for?
The International System of Units (SI) has two type of units, base units and derived units. Speed is a derived unit. Its unit is Meter/sec. Its a scalar quantity.
When comparing the speed of two objects why must you use the same units?
Speed consists of distance over time. You have to use the same measures of distance and time or the comparison is meaningless. You have to agree on the units in advance, or you have to convert to them.
How do you multiply seconds by meters divided by seconds?
You multiply speed by time. The units of time cancel out to give metres (distance) on its own

How many kilometer in two hours?
A kilometre is a unit of distance. An hour is a unit of time. Without some unit of speed to convert, the two units are incompatible.

Is it possible for two quantities to have the same dimensions but different units?
No. Measurement units are defined by and conversely. So the same units necessarily means same dimensions.
