1,65 / 514 (Tanjiro pixels) = 0,0032101167315175 meters per pixel

0,0032101167315175 x 258 (Sword pixels) = 0,828210116731515 meters

Blue = 269 px

Red = 94 px = 0,828210116731515175 meters (Sword height)

Purple = 377 px

To found the distance of Tanjiro and Ugiro and how many meters Tanjiro move to dodge:

0,828210116731515175 / 94 = 0,0088107459226721 meters per pixel

0,0088107459226721 x 269 = 2,370090653198795 meters

0,0088107459226721 x 377 = 3,321651212847382 meters

Results:

Blue = 269 px = 2,370090653198795 meters (Tanjiro dodged)

Red = 94 px = 0,828210116731515175 meters (Sword height)

Purple = 377 px = 3,321651212847382 meters (Distance between Tanjiro and Ugiro)

Distance: 3,321651212847382 m

Tanjiro dodged: 2,370090653198795 m

Attack speed: 332 m/s

3,321651212847382 / 332 = 0,0100049735326728

2,370090653198795 / 0,0100049735326728 = 236,891246684351 m/s

Subsonic+ speed.
