Pint to Pound Pengukuran Berdasarkan Ketumpatan
Misi Kami dan Metrologi

Tentang Pint to Pound

Ketahui jisim sebenar di sebalik isi padu. Ketepatan saintifik untuk perkiraan kulinari dan formulasi.

Mengapa Pint to Pound Dicipta

Pepatah bahawa 'satu pain bersamaan satu paun' terbukti salah secara fizikal untuk hampir semua bahan makanan.

Pain mengukur isi padu manakala paun mengukur jisim. Untuk air tulen pada 4°C, 1 pain cecair AS seberat 1.0432 paun. Tepung gandum hanya seberat 0.55 paun setiap pain, manakala madu mencecah 1.48 paun.

Pint to Pound menyingkirkan tekaan melalui formula ketumpatan fizikal (Jisim = Isi Padu × Ketumpatan) mengikut piawaian NIST dan USDA.

Prinsip Utama Kami

1. Ketelusan Metrologi

Semua data ketumpatan menyenaraikan sumber makmal, suhu rujukan, dan margin ketidakpastian.

2. Ketepatan Pelbagai Sistem

Membezakan secara tepat antara Pain Cecair AS (473.18 mL), Pain Imperial UK (568.26 mL), dan Pain Kering AS (550.61 mL).

3. Realisme Pertanian

Mengambil kira pecahan ruang rongga untuk buah-buahan segar daripada menganggapnya sebagai cecair seragam.

Pasukan Editorial dan Kawalan Kualiti

Pint to Pound ialah rujukan digital bebas untuk metrologi kulinari dan sains makanan.

Kami tidak menerima penajaan komersial. Setiap formula disahkan melalui proses ujian 3 fasa.

01
01. Primary Literature Grounding All ingredient densities are derived directly from empirical peer-reviewed databases (USDA FoodData Central, NIST Standard Reference Materials, or ASBC Methods of Analysis).
02
02. Temperature Normalization Volumetric thermal expansion coefficients are calculated for liquids, normalizing values to standard culinary laboratory conditions (20°C / 68°F under 1 atm).
03
03. Standard Reference Benchmarking Published laboratory datasets from NIST and USDA FoodData Central are cross-referenced to establish accurate density ranges and bulk packing void fractions across cultivars.

Authoritative Sources & Governance

Our calculations rely on internationally recognized metrology benchmarks:

  • National Institute of Standards and Technology (NIST): Handbook 44 & Special Publication 811.
  • USDA FoodData Central: Standardized food composition and laboratory bulk density metrics.
  • American Society of Brewing Chemists (ASBC): Specific gravity and hydrometer standards.
  • UK Weights and Measures Act 1985: Statutory Imperial gallon and pint legal definitions.

Correction Policy & Review Schedule

Our dataset undergoes continuous maintenance. If agricultural standards change, new cultivar packaging data is published by the USDA, or users identify an erratum, our team reviews and updates the relevant page within 48 hours.
