精度等级对照表通常用于描述测量仪器的精度水平。以下是常见的精度等级对照表,以微米(micrometers,μm)为单位:
| 精度等级 | 米(m) | 毫米(mm) | 微米(μm) | 纳米(nm) |
|---|---|---|---|---|
| 0.1 | ±0.1 | ±0.1 | ±100 | ±100 |
| 0.2 | ±0.2 | ±0.2 | ±200 | ±200 |
| 0.3 | ±0.3 | ±0.3 | ±300 | ±300 |
| 0.4 | ±0.4 | ±0.4 | ±400 | ±400 |
| 0.5 | ±0.5 | ±0.5 | ±500 | ±500 |
| 0.6 | ±0.6 | ±0.6 | ±600 | ±600 |
| 0.7 | ±0.7 | ±0.7 | ±700 | ±700 |
| 0.8 | ±0.8 | ±0.8 | ±800 | ±800 |
| 1.0 | ±1.0 | ±1.0 | ±1000 | ±1000 |
| 1.6 | ±1.6 | ±1.6 | ±1600 | ±1600 |
| 2.5 | ±2.5 | ±2.5 | ±2500 | ±2500 |
| 5.0 | ±5.0 | ±5.0 | ±5000 | ±5000 |
| 10.0 | ±10.0 | ±10.0 | ±10000 | ±10000 |
| 20.0 | ±20.0 | ±20.0 | ±20000 | ±20000 |
| 50.0 | ±50.0 | ±50.0 | ±50000 | ±50000 |
