National Odometer Day Hero
Arthur P. Warner
History of National Odometer Day
Traditionally a purely mechanical device, versions of the odometer appeared across history. Ancient Greece used specialists trained to measure footsteps and ancient Romans had their own versions of the odometers. Independent of these developments, odometers were also invented in the Han dynasty, in the form of a road carriage with a drum. As the story goes, each time the measurement of distance was met, a wooden figure would hit the drum. Experts consider this to be a highly advanced version of the odometer (considering the time) and cite this as the influence on the present odometer.
Multiple stories include the predecessor to the modern odometer as one developed for wagons and other horse-drawn vehicles to measure the distance they traveled. A special invention by a Mormon pioneer set the course for odometer development. William Clayton attached his device, a ‘roadometer,’ to his wagon that was heading west to Utah. This was followed by the invention of brothers Arthur and Charles Warner of the first odometer for an automobile, called the ‘auto-meter.’ The brothers went on to patent other items like the tachometer, a paper-making machine, an electric brake, and a power clutch. They also developed a thermometer for the motor but lost the patent to a lawsuit.
While technology has evolved over the ages, the odometer continues to record our distances traveled — only, it is now electronic.
National Odometer Day timeline
The first odometer, a road carriage with a drum, is invented in this period and is said to have influenced the birth of the modern odometer.
Before the odometer, distance in ancient Greece is measured by ‘bematists,’ or people specially trained to measure distances by counting steps.
Early descriptions of odometers are given by Hero of Alexandria and many more prominent figures.
These are developed for the automobiles of that age — wagons and other horse-drawn vehicles — to measure the distance they have traveled.
A Mormon pioneer named William Clayton invents this device, attaching it to his wagon while heading into Utah — National Odometer Day is celebrated on this very day!
Arthur P. and Charles H. Warner of Beloit, Wisconsin patent the first odometer for an automobile, which they call the ‘auto-meter.’
National Odometer Day FAQs
When is National Odometer Day?
In 2027, National Odometer Day falls on a Wednesday, May 12. This annual observance encourages drivers to appreciate their car’s mileage tracker and commit to regular maintenance.
How does an odometer work?
The odometer typically receives input from a sensor on the transmission or wheel hub, which sends pulses corresponding to wheel rotations. These pulses are then converted into distance units (miles or kilometers) and displayed on the dashboard, providing a cumulative record of the vehicle’s journey.
What is the average car mileage per year?
While 13,500 miles per year is a common average, individual mileage can fluctuate significantly. Factors such as remote work trends, fuel prices, and the availability of public transportation all influence how much a vehicle travels annually.
What is the difference between an odometer and a trip meter?
In contrast, a trip meter (or trip odometer) measures the distance traveled over a specific journey and can be reset by the driver at any time. It’s useful for tracking mileage for a single trip, fuel economy calculations, or service intervals.

5 Fun Facts About Odometers
The word 'Odometer' has Greek roots
‘Odometer’ is a combination of 'hodos,' which means ‘way’ or ‘path’ and 'metron,' which means 'measure.'
Different names, same machine
In different countries, odometers are called by various names like mileometer, milometer, or tripmeter.
Most modern cars have a trip odometer
Called a tripmeter, this machine can be reset at any point in a journey to help calculate the distance traveled at any point, unlike an odometer.
Modern cars have one, luxury cars have two
Many luxury vehicles have a pair of tripmeters.
Odometer law
In many countries (including the U.S.), the law requires vehicle mechanics to keep records of your odometer every time you service your vehicle.
Why We Celebrate National Odometer Day
We learn to appreciate our cars
They're responsible for taking us from point A to point B and everywhere in between, and yet, we do not know enough about our cars. Days like National Odometer Day give us a chance to learn about our vehicles and prompt us to take better care of them.
They write a memoir of our journeys
Odometers were invented to measure how far we traveled from our starting point. In a way, the modern odometer is a record of our trips and travels around the country.
It helps us spot fraud
These are rarely found in new cars anymore, but knowledge of odometer reading comes in handy when purchasing a used car. While tampering with the odometer to increase resale value is more common than you would think, learning about the odometer and, consequently, how to calculate the mileage means you are more likely to spot fraud.
