What is the scale ratio of 1mm equals 50km?

Answer 1

Convert the km to mm, then the units can be removed and the ratio found:

1 m = 1,000 mm

1 km = 1,000 m

= 1,000 x 1,000 mm

= 1,000,000 mm

⇒ 1 mm : 50 km

→ 1 mm : 50 x 1,000,000 mm

→ 1 mm : 50,000,000 mm

→ 1 : 50,000,000

Answer 2

1 to 50
