The invention discloses a frequency measuring method and a frequency measuring system. The frequency measuring method includes: latching pulse edges of input signals by means of clock signals to acquire pulse number Np and clock number Nc in sampling time, and computing pulse frequency P according to P=(NpxC)/Nc, wherein relative error by the frequency measuring method is +/-1/Nc. When in low frequency, the relative error +/-1/Np corresponding to +/- pulse signals in existing frequency measuring method is converted into +/-1/Nc equivalently, while the clock number Nc is much higher than the pulse number Np, namely +/-1/Nc is much smaller than +/-1/Np, and accordingly, accuracy is improved. When in high frequency, by setting reasonable unit timing time and being compared with existing period measuring method, the Nc is increased along with prolonging of periods of input signals in the unit timing time, while +/-/Nc is reduced, and accuracy is improved as well. Therefore, when in high frequency and low frequency, the frequency measuring method is higher in measuring accuracy as compared with the existing measuring method.
