About this conversion

Star Trek's original crew lists Walter Koenig (Chekov) at 5ft 6in (1.68m), William Shatner (Kirk) at 5ft 9in (1.75m), DeForest Kelley (McCoy) at 5ft 10.5in (1.79m) and Leonard Nimoy (Spock) at 6ft (1.83m), so Spock's three inches on Kirk showed in every bridge scene.

Heights come from IMDb bios (Shatner 5ft 9in, Kelley 5ft 10.5in, Koenig 5ft 6in) and Quora/Nimoy 6ft consensus. 1 Spock = 1.09x Chekov (1.83/1.68), 1 McCoy = 1.02x Kirk, making this converter a handy reference for casting debates, cosplay sizing and everyday curiosity.

Units supported: Meters, feet, and crew heights (Chekov 1.68m, Kirk 1.75m, McCoy 1.79m, Spock 1.83m).

Source note: Heights from IMDb cast bios — Shatner 5ft 9in, Kelley 5ft 10.5in, Koenig 5ft 6in — plus Nimoy 6ft.
