It represents a frequency of ten (10^1) hertz, which is a relatively low frequency. The prefix "deca" indicates a factor of 10^1, denoting a value that is ten times greater than the base unit. |

hectohertz | hHz | International System of Units (SI) / Metric System | A hectohertz (hHz) is a unit of frequency measurement in the International System of Units (SI). It represents a frequency of one hundred (10^2) hertz, which is a relatively moderate frequency. The prefix "hecto" indicates a factor of 10^2, denoting a value that is one hundred times greater than the base unit. |

kilohertz | kHz | International System of Units (SI) / Metric System | A kilohertz (kHz) is a unit of frequency measurement in the International System of Units (SI).
