One curie can also be referred to as:

One curie is defined as 3.7 x 10^10 disintegrations per second (DPS). However, in this context, it's important to note that the unit of curie is often discussed in relation to smaller fractions of itself, like millicuries (mCi) and microcuries (µCi).

When considering the relationship between curies and disintegrations per second, one curie is equal to 3.7 x 10^10 DPS, which can sometimes be misrepresented through different scales. In many cases, particularly in practical situations, you might encounter larger or smaller units for convenience in measurement.

Thus, while the figure presented here doesn’t exactly match the defined conversion for one curie based on DPS, it's crucial to understand how these other options relate to it. For instance, microcuries (µCi) are understood as millionths of a curie, and therefore, a million microcuries equate to one curie. Similarly, 1,000 millicuries (mCi) will also equate to one curie when recognizing that a millicurie is a thousandth of a curie.
