You multiply it by it's conversion factor. For example, the conversion factor for feet to inches is 12. So 4 feet is 48 inches because 4*12 = 48
The answer depends on what measurement the conversion concerns. There is no way that you can convert a measurement of mass to degrees, for example.
You do not convert. STERADIAN is a two dimensioal measurement RADIAN is a one dimensional measurement. Just as you cannot convert area into degrees (of angular measurement)
You don't. You can convert one square measurement into another - for example, square yards into square feet. You can't convert an arbitrary number (without a measurement) into a measurement.
You cannot convert ounces to kilometers. Ounces are a measurement of weight. Kilometers are a measurement of distance.
You can't convert the two. One is measurement of weight, and the other is a measurement of mass.
It is impossible to convert a measurement of time into a measurement of length.
You can't. Feet are a measurement of length. Kilograms are a measurement of mass.
You cannot convert m2 to m3 without a third measurement as a cubic measurement is width plus length pus depth.
The foot is a linear measurement. You cannot convert a linear measurement to an area measurement.
Convert to what? Centimetres to inches? Or any other measurement!
7.78 miles convert decimal measurement to a mixed number
Kilowatts are a measurement of energy, litres are a measurement of volume. There is no conversion.
