What the heck do I mean by that? Well, when I was in school, some instructors would look at the scores on their tests, expecting to see a "normal" (bell shaped) curve. If the center of the curve didn't line up with "average" performance, they might adjust the test scores. In other words, students were judged not just on their test scores alone but on how well they did in relation to the class as a whole. This is referred to as "grading on the curve."
So also, we can judge canister stoves not just on their weight alone but also on how their weights compare to other stoves in their class.
|Some stoves today weigh under one ounce, giving new meaning to the term "ultralight."|
Upright Canister Gas Stove
(Less Than or Equal To)
|Moderate||< 4||< 113|
|Light||< 3||< 85|
|Ultralight (UL)||< 2||< 57|
|Super Ultralight (SUL)||< 1||< 28|
Upright canister stoves today weigh as little as 25 grams – less than one ounce! There are five commercially available stoves that weigh less than two ounces.
Given the light weight of stoves available today, it's reasonable to insist on that a stove be truly light in order for it to belong to the class of "ultralight" and to be even more demanding of weight savings for a stove to earn the title "super ultralight."
|We assign meaning to terms like "light" and "UL" by categorizing stoves relative to one another.|

- SUL: If an upright canister stove weighs less than or equal to an ounce (28 g), it's super ultralight.
- UL: If a stove weighs less than or equal to two ounces (57 g) but more than one ounce, then it's ultralight.
- Light: If a stove weighs less than or equal to three ounces (85 g) but more than two ounces, then it's light.
- Moderate: If a stove weighs less than or equal to four ounces (113 g) but more than three ounces , then it's moderate.
- Heavy: If it weighs more than a quarter pound (4 oz/113 g), then, by modern standards, it's heavy.
Next time you read an ad or hear a salesman say that a three (or more) ounce stove is "ultralight," just nod your head and say "unh hunh, sure," and have yourself a little chuckle. Now, you know better.
