Distance Measure
June 9th, 2006
How can I measure distance on a graphic map?
I am using a graphic map with scale 1:250,000 and trying to measure the distance between two points but can’t figure it out.
Can someone help pleaseeeeeeee!
Thank you
It doesn’t matter whether you’re using metric or English measurements with a ratio scale, you just multiply what you measure to find the real world distance, just multiply by 250,000 and convert.
If you measure 2 inches
2 inches * 250,000 = 500,000 inches
500,000 inches / 12 ≈ 41,666.67 feet
41,666.67 feet / 5280 ≈ 7.89 miles
If you measure 2 cm
2 cm * 250,000 = 500,000 cm
500,000 cm / 100 = 5,000 m
5,000 m / 1,000 = 5 km
Isn’t that a whole lot neater? That’s why I love the metric system, although I just can’t seem to make myself THINK in the metric system, I always have to convert.
