Using Metric Prefixes (k, m) in Calculations

What the Prefixes Do

Metric prefixes let you type large numbers faster. Instead of typing out every zero, you append a short letter to a number and the mod expands it. The common ones are k for thousand and m for million, so 1k means one thousand and 5m means five million. This is the same shorthand used by the Not Enough Updates calculator, so it should feel familiar if you have used that mod.

Combining Prefixes With Operators

Prefixes work anywhere a number is accepted in an expression. You can mix them freely: 2k+500 adds five hundred to two thousand, and 10k/64 divides ten thousand by sixty-four. This is handy when you are budgeting bulk resources, since you can think in thousands or millions and let the mod handle the exact digits.

Practical Tips

Use prefixes when the exact figure matters less than the order of magnitude — for example, estimating how many items fit in a large storage system. If a result comes back with a prefix you did not expect, remember the mod is just formatting a normal number; the underlying value is exact. Avoid stacking two prefixes on one number, since that is not a valid expression and the search bar will fall back to treating your text as an item query.
