Features
Animal Crossing Calculator has two modes: a standard calculator and a unit converter.
 * Calculator – A basic calculator that can add, subtract, multiply, and divide numbers and percentages up to thirteen digits long. If the answer to the typed equation contains all of the same digit (e.g. 111), Tom Nook and flowers will appear on the top screen; if the answer contains only sequential digits (e.g. 123 or 321), Tom Nook and balloons will appear. The calculator keeps a history of past computations, which can be scrolled through with the L and R buttons.

 * Length – Can convert between centimeters, meters, kilometers, inches, feet, yards, and miles.
 * Area – Can convert between square meters, square feet, square yards, square miles, hectares, and acres.
 * Weight – Can convert between grams, kilograms, ounces, pounds, carats, and metric tons.
 * Speed – Can convert between meters per second, meters per minute, kilometers per hour, the speed of light, feet per second, miles per hour, knots, and mach.
 * Volume – Can convert between milliliters, liters, cubic meters, fluid ounces, gallons, and cups.
 * Temperature – Can convert between Celsius, Fahrenheit, and kelvin.
 * Time – Can convert between seconds, minutes, hours, days, weeks, years, and centuries.
