What is the formular for getting a new scale for a new map

To change the scale from 1:50,000 to 1:100,000, you need to reduce the scale. The new scale is less detailed, as it represents a larger area compared to the previous scale.

To perform this reduction, you would divide the numerator (the first number in the scale) by 2 and keep the same denominator (the second number in the scale). Therefore, the new scale would be 1:100,000.

Formula: New Scale = (Previous Scale numerator ÷ Reduction factor) : Previous Scale denominator

In this case, the reduction factor is 2 because we divided by 2 to go from 1:50,000 to 1:100,000.

Now, let's move on to the second question.

To change the scale from 1:100,000 to 1:20,000, you would need to enlarge the scale. The new scale would provide a more detailed representation of a smaller area.

To perform this enlargement, you would multiply the numerator (the first number in the scale) by a factor of 5, and keep the same denominator (the second number in the scale). Therefore, the new scale would be 1:20,000.

Formula: New Scale = (Previous Scale numerator × Enlargement factor) : Previous Scale denominator

In this case, the enlargement factor is 5 because we multiplied by 5 to go from 1:100,000 to 1:20,000.

To get a new scale for a new map, you would need to consider the desired level of detail or coverage area. The formula mentioned earlier can be used as a general guide to calculate the new scale. Adjust the reduction or enlargement factor based on the specific scale change you want to achieve.
