Multiplies vector by scalar: k·a⃗ = (ka₁, ka₂, ka₃). Scales magnitude by |k|, reverses direction if k < 0.
Scalar multiplication: k·a⃗ = (ka₁, ka₂, ka₃)
Magnitude: |k·a⃗| = |k|·|a⃗|
If k > 0: same direction
If k < 0: opposite direction
Scalar multiplication scales vector magnitude

Interpreting results
If scalar multiplication looks implausible, re-check units and which field is optional vs required.
Assumptions
- Scalar Multiplication is computed only from the fields you enter on this calculator. [scalar-multiplication-calculator]
- The wired execution function for `scalar-multiplication-calculator` is the source of numerical behavior.
- Matrix/vector shapes must match the operation implied by scalar multiplication.
Limitations
- Edge cases outside the intended domain of scalar multiplication may error or look unstable—treat them as out of scope.
- If multiple conventions exist for scalar multiplication, this calculator uses the convention implemented in its engine path.
- Ill-conditioned inputs can magnify error in scalar multiplication far beyond display precision.
Important note
