压力单位换算器 Pressure Converter
在 Pa、kPa、MPa、bar、psi、atm 等常用压力单位之间快速换算,适合胎压、气泵、液压与工程标注。
Convert pressure between Pa/kPa/MPa/bar/psi/atm for tire pressure, compressors, hydraulics, and engineering use.

怎么用(最常见用法) · How to use (most common):
在“压力数值”里输入数字,在“输入单位”选择你当前的单位(例如胎压表写的是 kPa 或 bar 或 psi),点击 “立即换算” 即可看到所有单位的换算结果。
Enter the value, pick the unit shown on your gauge/spec, then click Convert to get all units at once. -
胎压提示:表压 vs 绝压 · Tire pressure: gauge vs absolute
大多数汽车胎压表与车门贴纸标注的是 表压(Gauge pressure),也就是“相对于大气压的压力”。
Most tire gauges and vehicle door placards use gauge pressure (relative to ambient atmosphere).
本工具做的是“单位换算”,不判断表压/绝压;如果你拿到的是绝压(Absolute),请先确认是否需要减去当地大气压后再对照车辆推荐值。
This tool converts units only. If your source is absolute pressure, confirm whether you need to subtract ambient atmospheric pressure before comparing to recommended tire specs. -
bar 与 atm 很像,但不是同一个数 · bar vs atm (close but not equal):
1 bar = 100,000 Pa,而 1 atm = 101,325 Pa。两者相差约 1.3%。日常估算接近,但工程标注请用正确单位。
1 bar = 100,000 Pa while 1 atm = 101,325 Pa (~1.3% difference). Close for quick estimates, but use the correct unit in engineering work. -
psi 常见于北美胎压 · psi is common in North America:
如果你在加拿大/美国看到轮胎推荐值写 “35 psi”,可以直接输入 35 + 选择 psi,换算到 kPa/bar 用于国内设备。
If you see “35 psi” (US/Canada), enter 35 with unit psi to convert into kPa/bar for devices using metric units. -
mbar 与 hPa 的关系 · mbar and hPa:
在气象领域,1 mbar = 1 hPa(数值相同)。本工具提供 mbar,便于你把气象数据与工程单位互转。
In meteorology, 1 mbar equals 1 hPa (same numeric value). We include mbar to help you translate weather-related numbers to engineering units. -
复制功能 · Copy results:
每个结果卡片右上角都可以“复制”。需要一次性保存全部单位结果时,点击 “复制全部”。
Use “Copy” on any unit card, or “Copy all” to grab a full multi-line summary. -
输入异常提示 · Input validation:
若输入为空、不是数字,或数值过大导致显示异常,工具会在输入区下方提示错误。
If the input is empty/invalid (or extremely large causing display issues), an error message will appear under the input area.
