1. Calculating the scale of a map: To calculate the scale of a map, you can use the formula: Scale = Map Distance / Actual Distance. For example, if the map distance between two points is 5 cm and the actual distance between those points is 10 km, the scale of the map would be 1 cm = 2 km.
2. Calculating the scale of a model: If you are creating a scale model of a building, you would need to determine the scale factor. For example, if the actual height of a building is 100 meters and the height of your model is 10 centimeters, the scale factor would be 1:100.
3. Calculating the scale of a photograph: When working with aerial photographs or satellite images, you can calculate the scale by measuring a known distance on the image and comparing it to the actual distance on the ground. For example, if a road on the photograph measures 2 cm and the actual distance of the road is 200 meters, the scale of the photograph would be 1 cm = 100 meters.

1. Ratio Scale:
- Distance on a map: If 1 cm on the map represents 1 km on the ground, the scale is 1:100,000.
2. Interval Scale:
- Temperature: If the difference between 20°C and 30°C on a thermometer is the same as the difference between 40°C and 50°C, the scale is interval.
3. Ordinal Scale:
- Earthquake magnitude: If an earthquake with a magnitude of 7 is twice as intense as an earthquake with a magnitude of 5, the scale is ordinal.
4. Nominal Scale:
- Country names: If each country has a unique name, the scale is nominal.
Calculation Methods:
1. Representative Fraction (RF)
- Scale = RF = 1 / Distance on map (cm) : Distance on ground (km)
- Example: Scale = 1 / 0.1 cm : 10 km = 1:1,000,000
2. Verbal Scale
- Scale = 1 inch to (n) miles
- Example: Scale = 1 inch to 10 miles
3. Graphic Scale
- A bar on the map represents a known distance on the ground.
- Example: A 5-cm bar represents 100 km
4. Digital Scale
- Embedded in digital maps or GIS systems.
- Example: Scale = 1:50,000
- Distance on a map: If 1 cm on the map represents 1 km on the ground, the scale is 1:100,000.
2. Interval Scale:
- Temperature: If the difference between 20°C and 30°C on a thermometer is the same as the difference between 40°C and 50°C, the scale is interval.
