Conversely, 1 ppm on a 200 MHz NMR spectrometer corresponds to: 1 x 10-6 x 200 x 106 Hz = 200 Hz and 1 ppm on a 400 MHz NMR spectrometer corresponds to: 1 x 10-6 x 400 x 106 Hz = 400 Hz This ppm scale relative to TMS and the increasing value to the lower magnetic field (i.e., to the left from TMS) is called “the δ-scale.”

There are four carbons in the molecule and four peaks because they are all in different environments. But they aren't all the same height. In C-13 NMR, you cannot draw any simple conclusions from the heights of the various peaks.

NMR 1D Peaks Query Peaks are counted as a match if they are within .2 ppm for carbon and nitrogen atoms and if they are within .01 ppm for hydrogen atoms NMR Solvent data chart.
