noun
theoretical value
Used in scientific, engineering, and mathematical contexts to refer to a value predicted by theory, as opposed to an experimentally measured value.
この実験では、理論値と実測値がよく一致した。
In this experiment, the theoretical values agreed well with the measured values.
理論値からのずれを計算する。
Calculate the deviation from the theoretical value.
計算値 is a calculated value, which may be based on theory or a model, similar to 理論値 but sometimes used more broadly.
Compound of 理論 (theory) and 値 (value).
