An information processing apparatus includes a memory and a processor. The processor is configured to receive an input physical quantity, a value of the input physical quantity, and an output physical quantity. The processor is configured to generate a first array of first conversion operations or a second array of second conversion operations by using conversion rules each for converting a value of a source physical quantity into a value of a target physical quantity. Each conversion operation is a conversion according to a conversion rule or a reverse operation thereof. The first array enables a conversion of the input physical quantity into the output physical quantity. The second array enables the reverse. The processor is configured to convert the received value of the input physical quantity into a value of the output physical quantity by using the first array or the second array.
