Definition of spectrometer. 1 : an instrument used for measuring wavelengths of light spectra. 2 : any of various analytical instruments in which an emission (as of particles or radiation) is dispersed according to some property (as mass or energy) of the emission and the amount of dispersion is measured nuclear magnetic resonance spectrometer.
I meter is 39.37 inches. If you ignore the 0.37 inches, one meter is very close to 3.25 feet. Or, every 4 meters is very close to 13 feet. (Better than the cruder approximation of 1 meter = 3 feet, which would imply 4 meters =12 feet.) So, 1000 meters is 250 groups of 4 meters. So the answer is very nearly 250x13=3250 feet. Compare with the more exact answer given by Jonathan, 3280.84, about 1% more than 3250.
You entered Centimeters. These are additional conversions: To convert from meters to feet ( m to f ) is a simple conversion. You can use 1 m = 3.28 ft or 1 m = 39.37 inches and just multiply. But this converter is designed to convert an entry in meters into both feet and inches. The results are the total of feet and inches, not an answer in feet and an answer in inches separately.
