Selected category: angle.
Definition and details for flat:
Flat is an infromal unit of angle measure equal to the angle of the equilateral triangle (60 degrees), or one sextant (1/6 circle). For example a hex nut have 6 flat sides. So to turn the nut "one flat" is to turn it 1/6 revolution.
Definition and details for radian:
Radian (rad) is the SI unit of angle. It is a derived SI unit, defined as m⋅m-1, which means that angles are dimensionless. One radian is the angle at the center of a circle that cuts off an arc of length equal to the radius. Since the circumference equals 2 π times the radius, one radian equals 1/(2 π) of the circle, or approximately 57.296o.
