Tentang dek ini

Most SI lists are easy to scan and awkward to recall. These 110 text-only cards turn the complete core into small retrieval tasks: all seven base units and all 22 derived units with special names and symbols.

What the cards practice

  • Quantity ↔ unit and symbol: recall each base quantity and every named derived quantity in both directions.

  • Named unit ↔ coherent base-unit expression: expand all 22 special names, then reverse the mapping with the quantity supplied whenever an expression is shared.

  • Notation and distinctions: keep case, spacing, symbol grammar, Hz/Bq, Gy/Sv, rad/sr, and kelvin/degree Celsius intervals straight.

The deck leaves out prefixes, conversions, non-SI units, unnamed derived units, significant figures, uncertainty, laboratory procedures, historical definitions, defining-constant values, and proprietary exam material. Expression-to-unit prompts always state the quantity, so shared expressions such as s⁻¹ and m²·s⁻² stay unambiguous.

The sequence establishes the seven base units first. It then alternates the 22 named units with a deterministic stride before moving from identity recall to base-unit expressions. Related directions and easy-to-confuse units stay at least three unrelated cards apart; the review scheduler handles longer-term spacing after installation.

Facts were checked against the BIPM SI Brochure, 9th edition, version 4.01 and NIST SP 330 §2, with notation checked against NIST SP 330 §5. The 2026 BIPM edition expresses radian and steradian as unit one; this deck follows that current form. No source prose, third-party deck text, or exam content was copied.

An AI tool helped draft and sequence the cards and generated the cover. Every final front and back was manually checked against the official SI tables. The original questions, answers, selection, sequence, metadata, and cover are shared under CC0 1.0 to the extent those elements can be dedicated; the underlying SI facts remain common knowledge.

  103. Kartu 103

    Pertanyaan

    How are SI unit names capitalized in English?

    Jawaban

    They normally start with a lowercase letter, even when named after a person. Within this deck, the proper-name modifier in degree Celsius keeps its capital C.

  104. Kartu 104

    Pertanyaan

    What determines capitalization in an SI unit symbol?

    Jawaban

    Symbols derived from proper names start with a capital letter; the others are lowercase. Case is mandatory and meaningful.

  105. Kartu 105

    Pertanyaan

    Both gray and sievert reduce to m²·s⁻². What distinguishes them?

    Jawaban

    Gray (Gy) is used for absorbed dose or kerma; sievert (Sv) is used for dose equivalent. The quantity context determines the special name.

  109. Kartu 109

    Pertanyaan

    Radian and steradian both have coherent unit expression 1. What distinguishes them?

    Jawaban

    Radian (rad) is used for plane angle; steradian (sr) is used for solid angle. Their symbols preserve the quantity context.

  110. Kartu 110

    Pertanyaan

    For temperature intervals, how do kelvin and degrees Celsius compare?

    Jawaban

    A change of 1 K equals a change of 1 °C. Their zero points differ, so absolute temperatures aren't numerically equal.
