15 cm is longer.
In the USA, 15mm is half-inch, and 22mm is three-quarters inch. Lengths of pipe nipples in these sizes range from one and a quarter/one and a half, to six inches, in half-inch increments.
Then one is longer than the other.
(1/5) x 15 = 3 cm

To compare the lengths of the tapes, you would need to measure each tape and determine their respective lengths. If one tape is longer than the other, you can state the difference in length. Alternatively, if they are equal, you can conclude that the lengths are the same. Without specific measurements, a direct comparison cannot be made.
In the metric systems, unlike other systems, there is only one unit for each measurement; e.g the only unit for length is the metre. For lengths much longer, or shorter, lengths we use prefixes to indicate the fraction or multiple of the metre. For short lengths the fractions are thousandths, millionths, billionths; for which the prefixes are milli-, micro-, and nano-. For longer lengths, the multiples are thousands, millions, and billions; for which the prefixes are kilo-, mega-, and giga-. The prefixes indicate the fraction,or the multiple of the base unit.

If it measures a maximum of 30cm, which most rulers do it's 15cm.

One inch is 2.54 cm. One foot is 12 inches. Now you do the math.
