Step length: assign the length of one step of your character.
Meters: use this field if you can guess a certain distance in meters (when you don’t use the meter function). The Numbers of steps item will tell you how many steps the character needs to take to walk the indicated distance.
You can move, rotate and scale your character. By setting Scale accuracy you will have more control over this value. If it is activated you will not be able to type directly into the scale fields.
