Which physical dimension is source-backed for the SI unit s (Second)?

Answer options

• Option: length
  "length" vs. "time" Length is the physical dimension for SI; misses the target mapping. length stays thematically plausible but misses the requested target. The task targets this mapping, so length remains wrong in this prompt. length stays relevant in the graph profile but does not carry the requested relation.
• Option: mass
  "mass" vs. "time" Mass is the physical dimension for SI; misses the target mapping. mass stays thematically plausible but misses the requested target. The task targets this mapping, so mass remains wrong in this prompt. mass stays relevant in the graph profile but does not carry the requested relation.
• Correct: time
  "time" - target Time is the physical dimension for SI units such as the second. time matches the requested target of this prompt most precisely. The task targets this mapping, and time remains correct in this prompt. time remains tied to the requested relation through direct in the graph profile.
• Option: electric current
  "electric current" vs. "time" Electric current is the physical; misses the target mapping. electric current stays thematically plausible but misses the requested target. The task targets this mapping, so electric current remains wrong in this prompt. electric current stays relevant in the graph profile but does not carry the requested relation.

Solution

time

"time" is correct: Time is the physical dimension for SI units such as the second. The prompt targets time, so the graph keeps this mapping stable against close alternatives. Source: Wikidata. As of: 2026-02-13.

Fun fact

unit_dimension_match uses direct SI unit claims here, not conversion or symbol inference. time stays anchored with additional dataset context. The graph therefore uses a direct graph path.
