Tentang Pint to Pound

Ketahui massa akurat di balik volume: kalkulasi ilmiah presisi tinggi berdasarkan kerapatan fisik.

Mengapa Pint to Pound Dibuat

Pepatah bahwa 'satu pint sama dengan satu pon' terbukti tidak akurat secara fisik untuk hampir semua bahan makanan.

Pint mengukur volume dan pon mengukur massa. Untuk air murni pada 4°C, 1 pint cair AS berbobot 1,0432 pon. Tepung terigu hanya berbobot 0,55 pon per pint, sedangkan madu mencapai 1,48 pon.

Pint to Pound menggantikan perkiraan dengan rumus kerapatan fisik (Massa = Volume × Kerapatan) berdasarkan standar NIST dan USDA.

Prinsip Utama Kami

1. Transparansi Metrologi

Semua data kerapatan mencantumkan sumber laboratorium, suhu acuan, dan margin ketidakpastian.

2. Presisi Multi-Sistem

Membedakan secara akurat antara US Liquid (473,18 mL), UK Imperial (568,26 mL), dan US Dry Pint (550,61 mL).

3. Realisme Pertanian

Memperhitungkan fraksi rongga udara untuk buah segar daripada memperlakukannya sebagai cairan ideal.

Tim Redaksi dan Standar Kualitas

Pint to Pound adalah referensi digital independen untuk metrologi kuliner dan fisika bahan pangan.

Kami tidak menerima sponsor berbayar. Setiap rumus diverifikasi melalui proses pengujian 3 tahap.

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. 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. 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.
