Solutions for "fraction of a joule crossword clue" by Letter Count
3 Letters
ERG: A unit of energy, especially in the CGS (centimeter-gram-second) system, equivalent to 10-7 joules. It's a very small amount of energy, often encountered in physics and sometimes in scientific-themed crosswords.
More About "fraction of a joule crossword clue"
The clue "fraction of a joule" points directly to a smaller unit of energy. While the joule (J) is the standard unit of energy in the International System of Units (SI), many other units exist, especially from older systems like the CGS (centimeter-gram-second) system. The most prominent answer for this clue in crosswords is typically "ERG".
An erg is defined as the amount of work done by a force of one dyne acting over a distance of one centimeter. Its value of 10-7 joules indeed makes it a tiny fraction of a joule. This unit is less commonly used in modern physics than the joule, but its concise, three-letter spelling makes it a perfect fit for crossword puzzles, often appearing in science or general knowledge categories. Understanding such specific units can be key to unlocking tricky science-related clues in your puzzles.
Tips For Your Next Puzzle
- Think Scientifically: When clues involve units of measurement or scientific terms, consider lesser-known or older units that might fit the letter count. Many crosswords use these for variety.
- Consider Alternative Systems: Beyond SI units (like Joules, Meters, Kilograms), remember older systems like CGS (centimeters, grams, seconds) or imperial units, as clues might draw from them.
- Leverage Context: Look at the letters you've already filled in around the clue. Sometimes, one or two letters can strongly suggest a unique scientific term like ERG.
- Expand Your Vocabulary: Regularly reading about different fields, including science and history, can expose you to terms like 'erg' that are ripe for crossword clues.

Frequently Asked Questions
What is an erg in simple terms?
An erg is a very small unit of energy. Think of it as a historical alternative to the joule, used primarily in older scientific contexts. It represents a minuscule amount of energy or work.
Why is "ERG" a common crossword answer?
"ERG" is popular in crosswords because it's a short (three-letter), specific, and somewhat technical term. This combination makes it an ideal filler for grids, particularly for clues related to physics, energy, or units of measurement.
Are there other units that are a "fraction of a joule"?
While an erg is the most common crossword answer for this specific phrasing, other units are indeed smaller than a joule, such as millijoules (mJ) or microjoules (µJ), which are SI prefixes. However, these are less likely to appear as single-word crossword answers compared to the distinct unit "ERG."
