It means that if you enlarged the map enough, it would fit consistently over the land mapped. Maps not drawn to scale are used to show relationships between places without consistent measurements; this is common when the main thing being communicated is a route with landmarks and turns (in which case a 1-mile road can be drawn the same as a 2-mile road, as long as it's clear where the next landmark is), or a series of locations on a route network (for example a tourist map of a town may distort scale to fit outlying points of interest and show the roads used to reach them.
Not necessarily. Hand drawing gives you freedom, but then again with scale drawing, you get a more "finished" feeling i dont know the right word.

An underline on a dimension means that it is not to scale.
This means drawing something exact. For example, if in a test it was to say 'NOT drawn to scale' it would mean it isn't drawn correctly and wasn't reliable.
Scale is how much smaller(or bigger) the drawing is compared to the real object. It'd be real awkward if you were drawing a house to have to make the drawing as big as the house would be. But for the drawing to work out you need to know how to translate between the drawing and reality - so you decide something. Scale 1:12 for instance would mean that something that's one inch in the drawing would be one foot in reality.
The answer depends on what aspect of the scale drawing you wish to calculate.
It shows the constant of proportionality between the scale drawing and the real-life object.
it depends of the scale of the drawing
# is the ratio of the demensions in the drawing to the corresponding actual dimensions. The scale factor for a scale drawing is the ratio of the dimensions in the drawing to the corresponding acual bimensions.
scale questions
Scale provides the ability to measure a depicted feature or arrangement of features on the drawing, and scale it to what it was / will be in the real world. It is not always possible to dimension every possible feature, and a scaled drawing allows someone to infer what a given dimension will be.
Not all drawings are done to scale, sketches of buildings and people for instance. However if it is a technical drawing the draughtsman/woman will state on the drawing the scale used.
