In itself it is none of them - it is just a number.However if some units are attached, it can be any of them:If its units are a linear measure, eg 472 m, it is a lengthIf its units are a square measure, eg 472 sq cm, it is an areaIf its units are a weight measure, eg 472 kg, it is massIf its units are a time measure, eg 472 seconds, it is timeIf its units are a temperature measure, eg 472 K, it is temperature.
You can't convert that. You can only convert units that measure the same type of thing - for example, units of length to units of length, units of mass to units of mass, units of time to units of time, etc.
However you want: Speed is a measure of units of distance per units of time. Miles per hour or meters per second are common ones.
Units of electricity as given on power bills are usually measured in kiloWatt hours. (kW.h) This is a kiloWatt of energy delivered for a period of an hour. It is a unit of power, and a kiloWatt is a measure of energy.
The standard units used to measure the magnitude of physical quantities in physics are the International System of Units (SI units). These include units such as meters for length, kilograms for mass, seconds for time, and newtons for force.

A rate is:A comparison of two different units of measure!For example:Distance Traveled 70 Miles 2 Miles______________ = ______________ = ________=> The Time 35 Minutes 1 minuteAnswer: 2 miles: 1 minute!"You were speeding!"- TheUltimateMathGeek
We don't have enough time, or space to write it in.
Neither. These units measure distance and time, not speed.
