Question

Which pair of measurements is equivalent?

2,500 g, 250 kg
480 g, 4.8 mg
3.4 kg, 3,400 g
8,600 mg, 86 g

Answer 1

(c) 3.4 kg, 3400 g

Explanation:

k is the abbreviation for the SI prefix kilo-, meaning 1000.

m is the abbreviation for the SI prefix milli-, meaning 1/1000.

Translating the given quantities to the base unit (g), we can see which are equivalent.

a) 2500 g, 250×1000 g = 250000g . . . . not equivalent

b) 480 g, 4.8×0.001 g = 0.0048 g . . . . not equivalent

c) 3.4×1000 g = 3400 g, 3400g . . . . equivalent

d) 8600×0.001 g = 8.6 g, 86 g . . . . not equivalent
