A milk unit is any easy to use conversion from Imperial to Metric for measuring weight. People who have only used pounds (lbs) don’t have an easy way to understand how much an object my weigh in kilograms. However, most people familiar with pounds will also be familiar with gallons and will also understand what that amount of weight feels like. A gallon of liquid generally weighs around 3.75 kg, so two gallons would be 7.5 kg. This would be know as 2 MUs.
The flight has a strict carry-on restriction of 7.5 kilos. How much is that?
15lbs?
Yeah, but how heavy do you think my bag is?
Feels like it’s 2 Milk Units. You’re good.

Get the G-unitmug. Standard Sister-in-Law Unit
noun
*| \ ˈsta-ndərd ˈsi-stər-in-ˌlȯ yü-nət *
Abbreviation: SSILU
Symbol: 𝓢 or SIL
Definition:
An unofficial unit of mass equal to 300 pounds (136.08 kilograms), used to simulate high-risk, real-world human load scenarios in mechanical, structural, and transportation systems. The SSILU is commonly applied to test the failure thresholds of furniture, vehicle seats, elevators, bicycles, airline cabins, and public patience.
Etymology:
Originated in post-war American slang, the term is derived from the stereotype of a loud, heavyset female relative—often portrayed as emotionally volatile and structurally compromising—whose presence tests both family dynamics and infrastructure load-bearing capacity. While non-literal, the “sister-in-law” archetype evokes maximum physical and psychological mass concentration in civilian environments.
Technical Classification:
Measurement Type: Anthropomorphic Load Unit
Mass: 300 lbs (≈ 136.08 kg)
Field Use: Structural stress testing, emergency engineering simulation
Design Benchmark: Most consumer goods are not rated past 0.8 SSILU
