Fill Weight Calculator — Pouch, Bottle & Container

Sun, 01 Jun 2025 00:00:00 +0000

What is Fill Weight?

Fill weight is the mass of product filled into a container (pouch, bottle, tetra, tub). Accurate fill weight ensures:

Legal compliance: FSSAI requires net weight within ±3% of declared weight
Cost control: Overfill gives product away free
Consumer trust: Underfill is a legal violation

Formula

Fill Weight (g) = Fill Volume (mL) × Density (g/mL)

For milk and most fluid dairy products, density ≈ 1.028–1.032 g/mL

Product Expiry Date Calculator — Dairy & Food Shelf Life

📖 How to Use This Calculator

Mode 1 — Find Expiry Date: Enter the manufacturing date (or press "Today") + shelf life in days → get the exact expiry / best-before date.

Mode 2 — Check Validity on a Specific Date: Also fill in the Check Date field (e.g. a delivery or dispatch date) → the calculator tells you if the product will still be valid on that date and how many days remain.

ℹ️ Which convention should I use?

Exclusive (Recommended)

Manufacture date is Day 0. The shelf life clock starts the day after manufacture.
Example: Manufactured 14/07/2026 + 180 days = expires 10/01/2027.
Used by: IS 1479, most FSSAI product standards, Codex Alimentarius, EU food law.

Inclusive

Manufacture date is Day 1. The shelf life clock starts on the day of manufacture itself.
Example: Manufactured 14/07/2026 + 180 days = expires 09/01/2027.
Sometimes used when: the label says "Best Before 180 days from date of manufacture" and the pack date is interpreted as day 1.

💡 When in doubt, use Exclusive — it gives a slightly longer (more conservative) shelf life and aligns with standard Indian dairy industry practice.
