WebSep 18, 2024 · Though it can be "dimensionless" like an angle, which is the ratio of two lengths if measured in radians. Of course you can also decide to introduce a new unit like the degree (right angle ##90^{\circ}##). In principle there's even the possibility to introduce a system of units where all quantities are dimensionless (Planck units). WebThe results of twist angle is indeed dimensionless, but so are radians! The radian is defined as the ratio of arc length to radius length, so both arc length and radius length have the same unit, then they cancel each other. It's common for many dimensionless quantities in engineering and physics to use radians. You'll get used to it. daewoo warranty registration
