An odometer is the counter in a vehicle that tells you how far it has already gone, in miles or kilometres. In a car it is the number that keeps climbing.

Many cars also have a trip odometer, a second counter you can set back to zero for one journey. It measures distance, not speed — that other dial, the one that jumps when you go faster, is the speedometer.

Though actually, learners mix those two up all the time, and even some English speakers are sloppy about the names.

People sometimes stretch it to any little device that counts how far you have walked or ridden, but the home of the word is still the dashboard. In older cars it was rolling numbers; now it is often a number on a screen.

People sometimes stretch it人們有時候會把這個字延伸 to any little device用到任何小裝置上 that counts how far you have walked or ridden計算你走了或騎了多遠的, but the home of the word但這個字真正的家 is still the dashboard還是儀表板。In older cars在舊車上 it was rolling numbers它是滾動的數字; now現在 it is often a number on a screen則常常是螢幕上的一個數字。

When someone secretly turns the number back on a used car to make it look newer, they are tampering with the odometer — that is dishonest, and in many places it is against the law. It is a plain, practical noun, not slang and not fancy.
