Question

The motorcycle engine on a Kawasaki Ninja 1000 has a displacement of 1043 cubic-centimeters (cm3). In order to calculate its engine displacement in cubic-inches (in3) what unit conversion factor would you use to multiply the given displacement?
A. 1 in3 / 16.4 cm3
B. 2.54 cm3 / 1 in3
C. 1 in3 / 2.54 cm3
D. 6.45 cm3 / 1 in3

Answer 1

Answer:

A. 1 in³ / 16.4 cm³

Explanation:

Inches is an imperial unit while centimeter is a metric unit.

1 inch = 2.54 cm

⇒1 inch³ = 2.54³

⇒1 inch³ = 2.54×2.54×2.54

⇒1 inch³ = 16.38 cm³ = 16.38 cc

So,

$1\ cc=\frac{1}{16.38}\ inch^{3}$

$1043\ cc=1043 \frac{1\ inch^3}{16.38\ cm^3}\\\Rightarrow 1043\ cc= 63.67\ inch^3$

So,  1 in³ / 16.4 cm³ conversion factor should be used.
