How do you calculate a conversion rate?
Conversion rates are calculated by simply taking the number of conversions and dividing that by the number of total ad interactions that can be tracked to a conversion during the same time period. For example, if you had 100 conversions from 1,000 interactions, your conversion rate would be 10%, since 100 ÷ 1,000 = 10%.
What is a calculator?
According to Wikipedia: A calculator is a machine that allows people to do math operations more efficiently. For example, many calculators will add, subtract, multiply, and divide. Some also calculate square roots, and more complex calculators can help with calculus and draw function graphs. Calculators are ubiquitous. Smartphones and other computers can also serve as a calculator.
Some calculators, such as the abacus, will work without requiring batteries. Others, like the electronic calculator, need batteries. There are two main types of electronic calculators: simple calculators—which can only add, subtract, multiply and divide, and sometimes take square roots—and scientific calculators—which can do many other things, such as calculate factorials and trigonometry functions.
