Translation guide
The English word 'immeasurable' describes something so vast or great that it cannot be measured. In Japanese, this concept is expressed through adjectives, verbs, and set phrases that emphasize boundlessness, infinity, or inestimable value. The most common and versatile equivalent is 計り知れない (hakari shirenai), which directly means 'cannot be measured' and is used for both abstract and concrete things. Other options carry nuances of infinity, vastness, or pricelessness.
Expressing that something is so large, deep, or significant that it cannot be quantified or fully understood.
Literally 'cannot be measured'. This is the most direct and common translation for 'immeasurable'. It is used for both abstract concepts (e.g., influence, sorrow) and concrete things (e.g., distance, amount). It often carries a nuance of awe or profundity.
彼の影響力は計り知れない。
His influence is immeasurable.
その悲しみは計り知れない。
The sorrow is immeasurable.
Means 'infinite' or 'limitless'. Often used in mathematical, scientific, or philosophical contexts, but also for abstract qualities like love or possibilities. It emphasizes the absence of boundaries rather than the inability to measure.

The universe is immeasurably vast.
彼の才能は無限だ。
His talent is immeasurable.
Means 'enormous' or 'vast', often used for amounts, wealth, or expenses. It implies a scale so large it is hard to grasp, but it is more concrete than 計り知れない. It is not typically used for abstract qualities like love or sorrow.
そのプロジェクトには莫大な費用がかかった。
The project cost an immeasurable amount of money.
Means 'immeasurable' or 'boundless', often used in Buddhist contexts or formal writing. It appears in set phrases like 無量の感慨 (immeasurable deep emotion). Less common in everyday speech.

To be immersed in immeasurable deep emotion.
Describing something of such great worth that it cannot be assigned a value.
The phrase 'immeasurable value' is directly translated as 計り知れない価値. It is natural and commonly used.
この経験は計り知れない価値がある。
This experience has immeasurable value.
Means 'precious' or 'valuable'. It is often used for things that are rare or important, but it does not inherently mean 'immeasurable'. To convey the nuance of immeasurability, it is often combined with 計り知れない or used in context.
貴重な時間を無駄にした。
I wasted immeasurably precious time.
Means 'unique' or 'unparalleled', often used in the phrase 無二の親友 (one's best and only friend). It can imply immeasurable value due to uniqueness, but it is limited to specific collocations.
Emphasizing the depth or intensity of feelings, gratitude, or abstract qualities.
While 深い simply means 'deep', it is often used in Japanese where English would use 'immeasurable' for emotions. For example, 深い悲しみ (deep sorrow) is more natural than 計り知れない悲しみ in many contexts, though both are possible.
深い感謝の気持ちでいっぱいです。
I am filled with immeasurable gratitude.
計り知れない (hakari shirenai) is the most versatile and directly corresponds to 'immeasurable' in the sense of 'cannot be measured'. It works for both abstract and concrete things. 無限 (mugen) means 'infinite' and emphasizes boundlessness rather than the inability to measure; it is common in scientific or philosophical contexts. 莫大 (bakudai) means 'enormous' and is used for large amounts or sums; it is more concrete and less emotional.
While 測れない (hakarenai) literally means 'cannot be measured', it is not used in the same figurative sense as 'immeasurable'. The phrase 計り知れない is the correct idiomatic expression. Using 測れない would sound like a physical measurement is impossible, not that something is vast or profound.
その発見の影響は計り知れない。
The impact of the discovery is immeasurable.
彼女は計り知れない喜びを感じた。
She felt immeasurable joy.
He is an immeasurably important person to me.
A formal phrase meaning 'indescribable' or 'beyond words'. It is used for emotions or experiences that are so profound they cannot be expressed, similar to 'immeasurable' in emotional contexts.

Its beauty is immeasurable (beyond words).
