In this paper, our goal is to focus on the determination of these parameters for a sample of K and M dwarfs. In a future paper (PaperII; Houdebine+, 2017, J/ApJ/837/96), we will combine our rotational data with activity data in order to construct RACs. Here, we report on a determination of effective temperatures based on the (R-I)C color from the calibrations of Mann+ (2015, J/ApJ/804/64) and Kenyon & Hartmann (1995, J/ApJS/101/117) for four samples of late-K, dM2, dM3, and dM4 stars. We also determine stellar parameters (Teff, log(g), and [M/H]) using the principal component analysis-based inversion technique for a sample of 105 late-K dwarfs. We compile all effective temperatures from the literature for this sample. We determine empirical radius-[M/H] correlations in our stellar samples. This allows us to propose new effective temperatures, stellar radii, and metallicities for a large sample of 612 late-K and M dwarfs. Our mean radii agree well with those of Boyajian+ (2012, J/ApJ/757/112). We analyze HARPS and SOPHIE spectra of 105 late-K dwarfs, and we have detected vsini in 92 stars. In combination with our previous vsini measurements in M and K dwarfs, we now derive P/sini measures for a sample of 418 K and M dwarfs. We investigate the distributions of P/sini, and we show that they are different from one spectral subtype to another at a 99.9% confidence level. Description: We selected a sample of 419 late-K dwarfs on the basis of (R-I) measurements available in the literature. Searching through databases at the European Southern Observatory (ESO) and Observatoire de Haute Provence (OHP), we identified spectra of 112 different stars that are suitable for our purposes. The spectra that we use to determine vsini came from two different echelle spectrographs: HARPS (High Accuracy Radial velocity Planet Search, ESO; R=115000) and SOPHIE (OHP; R=75000). File Summary:
