The answer is 21 Hertzs is equal to 21000 Millihertzs and that means we can also write it as 21 Hertzs = 21000 Millihertzs. Feel free to use our online unit conversion calculator to convert the unit from Hertz to Millihertz. Just simply enter value 21 in Hertz and see the result in Millihertz. You can also Convert 22 Hertzs to Millihertzs
By using our Hertz to Millihertz conversion tool, you know that one Hertz is equivalent to 1000 Millihertz. Hence, to convert Hertz to Millihertz, we just need to multiply the number by 1000. We are going to use very simple Hertz to Millihertz conversion formula for that. Pleas see the calculation example given below.
\(\text{1 Hertz} = \text{1000 Millihertzs}\)
\(\text{21 Hertzs} = 21 \times 1000 = \text{21000 Millihertzs}\)
Hertz is a unit of measurement for frequency. Hertz is named after Heinrich Rudolf Hertz because he was the first person who provided conclusive proof of the existence of electromagnetic waves. Something which happens once per second is defined as 1 hertz. One hertz is equal to 360 degrees per second.
The symbol of Hertz is Hz. This means you can also write one Hertz as 1 Hz.
Millihertz is a unit of measurement for frequency. Millihertz is a decimal fraction of frequency unit hertz and one millihertz is equal to 0.001 hertz.
The symbol of Millihertz is mHz. This means you can also write one Millihertz as 1 mHz.
