Translation guide
The force exerted by air, either in a scientific context (atmospheric pressure) or in everyday situations (tire pressure, compressed air).
The pressure of the atmosphere, often discussed in weather forecasts or scientific contexts.
The standard term for atmospheric pressure. Used in weather reports and scientific contexts.
今日は気圧が低いです。
The atmospheric pressure is low today.
気圧の変化で頭痛がします。
I get headaches from changes in air pressure.
More technical term for atmospheric pressure, often used in physics or engineering.
大気圧は海面で約1013ヘクトパスカルです。
Atmospheric pressure is about 1013 hectopascals at sea level.
The pressure of air inside a tire, often checked at gas stations or before driving.
The most common term for tire pressure. Literally 'air pressure' but specifically used for tires, balls, etc.
タイヤの空気圧をチェックしてください。
Please check the tire pressure.
空気圧が低いと燃費が悪くなります。
If the tire pressure is low, fuel efficiency gets worse.
A more casual way to refer to tire pressure, literally 'the air in the tires'.
タイヤの空気が足りないみたい。
It seems like the tires are low on air.
The pressure of air used in pneumatic tools, air compressors, or industrial settings.
Also used for compressed air pressure in tools and machinery.
この機械は空気圧で動きます。
This machine runs on air pressure.
Abbreviation of 'air pressure', common in technical or hobbyist contexts.
エア圧が下がってきた。
The air pressure is dropping.
The pressure of air inside a sealed object like a ball or balloon.
Used for any enclosed air pressure, such as in sports balls.
ボールの空気圧を調整する。
Adjust the air pressure of the ball.
気圧 (kiatsu) is used for atmospheric pressure in weather and science. 空気圧 (kuukiatsu) is used for the pressure of air in tires, balls, or machines. Using 気圧 for tire pressure would sound odd.
天気予報で気圧の谷が近づいていると言っていた。
The weather forecast said a trough of low pressure is approaching.
自転車の空気圧が低いので、空気を入れないと。
The bicycle tire pressure is low, so I need to pump it up.
