NumberCompose[{c1, ..., cn}, {u1, ..., un}] returns the quantity c₁u₁ + ... + cₙuₙ.

Examples

Compose a number from units:

NumberCompose[{3, 2, 5}, {100, 10, 1}]
(* 325 *)

Time composition:

NumberCompose[{2, 30, 45}, {3600, 60, 1}]
(* 9045 seconds *)

With unit objects:

NumberCompose[{5, 3}, {Quantity[1, "Meters"], Quantity[1, "Centimeters"]}]
