To make the conversion we must take into account the relationship between kBq and microcuries. Both are units that represent radioactivity activity. The relationship is:
1 kilobecquerel (kBq) = 0.027027027 microcurie
Therefore, 2.6kBq will be equal to:
Answer= That activity in microcuries will be 0.070 microcuries
