Manufacturers use different terms to identify engine displacement. Basically, they use a metric cubic centimeter (cc) or a USA cubic inch (ci) term. This can confuse many people when it is time to choose an engine. With this chart, you’ll be able to convert the most popular engines on the market.
.12ci = 2.0cc
.15ci = 2.5cc
.18ci = 3.0cc
.20ci = 3.3cc or 3.4cc depending of the manufacturer
.21ci = 3.46cc, 3.48cc or 3.5cc depending of the manufacturer
.23cc = 3.78cc
.24ci = 3.975cc
.25ci = 4.1cc
.26ci = 4.26cc
.27ci = 4.4cc
.28ci = 4.6cc
.30ci = 4.9cc
.32ci = 5.2cc
.36ci = 5.9cc
.46ci = 7.7cc
.50ci = 8.0cc
