But if you are measuring 1 inch, +/-2.5 ppm is 1 inch plus or minus 0.0000025 inches. If you are measuring 10 inches, +/- 2.5ppm is plus or minus 0.000025 inches. The energy axis is called a δ (delta) axis and the units are given in part per million (ppm). Most often the signal area for organic compounds ranges from 0-12 ppm.

The protons of alkenes are deshielded and their signals appear downfield from the saturated C-H protons in the 4-6 ppm range. There are two reasons for this. First, sp2 hybridized carobs are more electronegative than sp3 carbons since they have more s character (33% vs 25% s). 1. ppm: gas volume percentage per million, it is a dimensionless unit. i.e.: 5ppm carbon monoxide means that the air contains 5 per million of carbon monoxide.
