On the ground one-half mile is the same as 4.4 inches on the map. Some bra and girdle styles may fit smaller or larger than what your actual measurements indicate. Measured distance = 2,640 feet 1 inch = 4.4 inches Step 2. Use the map scale from Example 6 to find the map distance. Measured distance = known distance / map scale Step 1. Set up the cancellation table so all units will cancel, except the desired unit, feet. Rearrange terms by multiplying each side by the measured distance and dividing each side by the map Map scale = known distance / measured distance How many inches is does this distance correspond to on the map? The known ground distance between points B and C is 1/2 mile. What is the scale in units of inches/foot?Įxample 5 - Use the map scale in example 6. Also, if a map has section lines, the distance between section lines is typically 1 mile.Įxample 4 - The distance between point A and B is 6 inches on the map. The scale can be calculated by knowing the distance between two points on the map, and measuring the distance on the map. Occasionally, a map may not provide a scale. Step 3. Set up the cancellation table so all units will cancel, except the desired unit, inches.ġ2,000 feet = 182 chains = 2.3 miles = 144,000 inches Step 2. Set up the cancellation table so all units will cancel, except the desired unit, miles. Step 1. Set up the cancellation table so all units will cancel, except the desired unit, chains. Example 3b - Using the information in Example 3a, find the ground distance in chains, miles, and inches.Multiply the total number of dots by the conversion factor on the map scale to determine the total acreage. Count every other dot when dots fall on the boundary line. Place the acreage grid transparency over the area to be measured.Ĭount dots inside the sketched area. Want to know the actual size of a 1 carat diamond on a hand Use our diamond size chart to understand the millimeter (mm) size of each diamond shape. Table 5.2 Acreage Grid Overlay, Map Scales, and Equivalents. Eau de Toilette: 515 pure essence and lasts for about 3 hours. To use the acreage grid transparency, follow these steps: Eau de Parfum: Lasts 5 to 8 hours and is 1520 pure essence. USING THE MODIFIED ACREAGE GRID (TRANSPARENCY) Set up the cancellation table so all units will cancel, except the desired unit, feet. Step 1. Set up the cancellation table so all units will cancel, except the desired unit, miles/inch.Įxample 3a - The map distance between two points is 6 inches. On the map 1 inch is equal to 2,000 feet on the ground, 1:2,000 (in/ft).Įxample 2 - Convert the 1:2,000 (in/ft) to (in/mile). Step 1. Set up the cancellation table so all units will cancel, except the desired unit, ft/in. Ground distances on maps are usually given in feet or miles.Įxample 1 - Convert the map scale of 1:24,000 (in/in) to (in/ft). For example, a map scale indicating a ratio of 1:24,000 (in/in), means that for every 1 inch on the map, 24,000 inches have been covered on the ground. It is given as a ratio of inches on the map corresponding to inches, feet, or miles on the ground. The map scale is printed in the map legend.
