SI Unit Rendering Test

Testing improved SI unit rendering with thin spaces instead of centered dots, and regular superscripts instead of unicode.

Basic Units with Powers

Test 1: kg·m² (the original example)

\SI{5}{kg.m^2}

Test 2: Negative exponents (user's example)

\SI{5}{kg.m^2.s^{-3}.A^{-1}}

Test 2b: Acceleration

\SI{9.8}{m.s^{-2}}

Test 3: Complex unit (Joule)

\SI{100}{kg.m^2.s^{-2}}

Test 4: Just unit without value

\si{kg.m.s^{-1}}

Test 5: Scientific notation with units

\SI{6.626e-34}{J.s}

Test 6: Simple unit (meter)

\SI{100}{m}

Test 7: Prefix with power

\SI{50}{km^2}
