Difference Between Omron HJ-112 and HJ-113
The difference between the Omron HJ-112 and the Omron HJ-113 is a major debate on the Net. Some say that the HJ-113 is a metric pedometer, but that is not what the instruction book on the Omron website shows.
Another discussion on the Net says the HJ-113 is thicker and heavier.
Let’s bust the myths and find the truth about the difference between the HJ-112 and HJ-113.
The best sources for a comparison are found in the instruction manuals for the two pedometers on the Omron website. These are available in PDF format so we can download them and study them in detail. The manual for the HJ-112 is single page in the display, but for some reason, Omron displays the manual for the HJ-113 as two pages side by side which makes the print fuzzy when you zoom in so you can read it.
The first thing you notice from the picture in the manuals is the HJ-112 has four buttons and the HJ-113 has three buttons. The HJ-113 is missing the “Reset Button”. Also, on the HJ-112 the label on the “Memory” button is spelled in full. On the HJ-113 the button is abbreviated as “Memo”. The memory function is the same on both units.

Each manual has a specification page that lists all the specs for each unit so let’s study the them.

The differences between the two units are:
- the differences in buttons previous mentioned.
- the HJ-113 calculates the amount of fat burned and the HJ-112 does not.
- the HJ-113 has an operating humidity specification and a “Storage Temperature/Humidity/Air Pressure” and the HJ-112 does not.
- the dimensions of the two units are different. The HJ-112 is more oval shaped than the HJ-113. Both units are the same thickness.
- the HJ-113 is 0.11 ounces lighter than the HJ-112 with battery included.
This table sums up the differences. Bottom line – you can buy the Omron HJ-113 for less than the Omron HJ-112 on Amazon.

The Omron HJ-113 is overshadowed by the more popular HJ-112, but in reality, the HJ-113 does basically the same thing as the HJ-112 and costs less.
