精密 vs 精细 (jīngmì vs jīngxì): precise instruments vs meticulous detail
Both 精密 and 精细 describe something precise or fine, but they differ in context: 精密 emphasizes high accuracy and strict margins in scientific, mechanical, or technical settings (e.g., instruments, calculations), while 精细 focuses on careful, detailed workmanship, craftsmanship, or refined management (e.g., embroidery, planning). Choosing the wrong term can sound unnatural or inaccurate.
The words 精密 and 精细 both convey the idea of 'fine' or 'precise', but they apply to different domains. 精密 is used for objective, measurable precision in fields like engineering, science, and medicine, often describing equipment, instruments, or numerical data. 精细 describes subjective, qualitative refinement in items, tasks, or processes that require careful attention to detail, such as handicrafts, artwork, or meticulous analysis. While there is overlap in some contexts (e.g., careful work), the collocations are distinct: 精密 collocates with 'machine', 'instrument', 'calculation', and 精细 collocates with 'workmanship', 'description', 'management'.
When to use each
Use 精密 when referring to high accuracy in scientific, mechanical, or technical contexts, such as precision instruments, measurements, or complex calculations. It emphasizes strict tolerances and exactness, often involving machinery or quantitative data.
精密 can also describe highly detailed plans or systems (e.g., 精密的计划), but always with a sense of exactness rather than aesthetic fineness.
Use 精细 for describing the careful, thorough, and deliberate attention to detail in craftsmanship, artwork, or management. It focuses on the fineness of execution, such as in embroidery, carving, or a detailed analysis.
精细 can also be used for food preparation (e.g., 精细的菜肴) to indicate intricate or refined cooking, but not for mechanical precision.
At a glance
| 精密 | 精细 | |
|---|---|---|
| Primary domain | Science/engineering (objective precision) | Craft/art/management (subjective meticulousness) |
| Typical nouns | 仪器 yíqì (instrument), 计算 jìsuàn (calculation), 机械 jīxiè (machinery) | 做工 zuògōng (workmanship), 刺绣 cìxiù (embroidery), 分工 fēngōng (division of labor) |
| Implication of error | Measurable tolerance (tiny deviation is unacceptable) | Aesthetic or qualitative flaw (lack of care or detail) |
| Degree of fineness | Strict, exact, quantifiable | Careful, fine, nuanced |
Examples
- 精密这台精密仪器需要定期校准。Zhè tái jīngmì yíqì xūyào dìngqī jiàozhǔn.This precision instrument needs regular calibration.Correct collocation: 精密 + 仪器 (instrument).
- 精细她的刺绣非常精细，每一针都很到位。Tā de cìxiù fēicháng jīngxì, měi yī zhēn dōu hěn dàowèi.Her embroidery is very meticulous; every stitch is perfectly placed.Correct collocation: 精细 + 刺绣 (embroidery).
- 精密科学家进行了精密的计算。Kēxuéjiā jìnxíngle jīngmì de jìsuàn.The scientist carried out precise calculations.Use 精密 for calculations involving exact numbers.
- 精细这个工匠的做工非常精细，连最细小的花纹都雕刻得很清楚。Zhège gōngjiàng de zuògōng fēicháng jīngxì, lián zuì xìxiǎo de huāwén dōu diāokè de hěn qīngchǔ.This craftsman's workmanship is very meticulous; even the tiniest patterns are carved clearly.Workmanship is typically described with 精细, not 精密.
- 精密这台机械的零件加工需要非常精密。Zhè tái jīxiè de língjiàn jiāgōng xūyào fēicháng jīngmì.The machining of this machine's parts requires very high precision.Mechanical parts often require 精密加工 (precision machining).
- 精细她的管理方式非常精细，每一笔开支都有记录。Tā de guǎnlǐ fāngshì fēicháng jīngxì, měi yī bǐ kāizhī dōu yǒu jìlù.Her management style is very meticulous; every expense is recorded.Management can be 精细 (meticulous), but not 精密.
Common mistakes
- Using 精细 to describe a scientific instrument: ✗ 这个精细的仪器 — use 精密 instead.
- Using 精密 to describe delicate embroidery: ✗ 她的刺绣很精密 — use 精细.
- Saying '精密的计划' when the plan is just thorough and not mathematically exact; if it's a detailed plan, 精细的计划 is more natural.
- Confusing 精密 with 'precise' in a general non‑technical sense: 精密的描述 sounds odd; use 详细的描述 or 精确的描述.
FAQ
- When do I use 精密 vs 精细?
- Use 精密 for mechanical, scientific, or technical precision (e.g., instruments, calculations). Use 精细 for careful workmanship, detailed analysis, or refined craftsmanship (e.g., embroidery, management). Think: '精密 = high accuracy' vs '精细 = fine detail'.
- Can 精密 and 精细 be used interchangeably?
- Rarely. They are not true synonyms. In the rare case of describing a 'detailed plan', both might work, but 精密 stresses exactness while 精细 stresses thoroughness. For most objects, only one is idiomatic: 精密仪器 but 精细做工.
- Are there other similar words like 精确 (jīngquè)?
- Yes. 精确 (jīngquè) means 'accurate' and focuses on correctness of data or results, not the tool itself. For example, 精确的计算 (accurate calculation) vs 精密的计算 (precise calculation using fine‑grained methods). 精密 is more about the equipment or process; 精确 about the outcome.
