Introduction

In the episode "Eva Needs to Measure," Alex Goldman delves into the complexities of measurement systems, sparked by Eva Higginbotham's struggle to convert American baking measurements for use in the UK. This episode explores the technical and cultural discrepancies between the US customary units and the metric system, highlighting the challenges faced by individuals navigating these differences in everyday tasks like baking.

Eva’s Problem: Navigating Measurement Systems

The episode begins with Alex introducing Eva Higginbotham, a neuroscientist and podcast producer based in London who grapples with converting American recipes that use volume measurements (cups) into the metric system (grams) commonly used in the UK.

Eva Higginbotham [01:18]:
"I've been baking American recipes since I first started baking. Right from when I was like 11 and got into it. I was using my mum's cookbooks. And the problem is that obviously in America, things are measured in cups and that's a volume. In England, we measure things in grams."

Eva explains the inconsistency in online conversions, where searching for the weight of a cup of butter yields multiple, varying results, making precise baking challenging.

Eva Higginbotham [02:48]:
"Someone should have decided how much a cup of butter weighs. So I feel like maybe the problem is no one's. Like, there's no oversight over how much something is."

Understanding Measurement Units: Volume vs. Weight

Alex highlights the fundamental difference between the US and UK measurement systems: volume (cups) versus weight (grams). He acknowledges his own lack of awareness about these differences despite his familiarity with baking shows.

Alex Goldman [03:21]:
"You measure stuff in grams. So, like, you measure it as weight instead of volume?"

Eva Higginbotham [03:24]:
"Especially things like butter that's very hard to fill up a cup with unless you melt it."

Eva describes her method of using a kitchen scale to achieve precise measurements, emphasizing the importance of accuracy in baking, especially for special occasions.

Eva Higginbotham [05:18]:
"Especially if you're, like, putting the time and effort to, like, make something delicious. Maybe it's someone's birthday... what if using the wrong reference for the butter conversion is going to ruin the cake."

Expert Insights: The Role of Measurement Standards

To tackle Eva's dilemma, Alex consults Doreen El Haddad, a physicist from the National Institute of Standards and Technology. Doreen explains the historical context of measurement standards and introduces "Le Grand Coeur," the international prototype of the kilogram created in the late 1800s to standardize measurements globally.

Doreen El Haddad [07:34]:
"In France, every village had their own thing, and it was like the length of the arm of the king... they wanted to standardize things to simplify trading."

However, Doreen clarifies that minor inconsistencies, such as mass drift due to environmental factors, are negligible for everyday use and do not account for the significant variability Eva experiences.

Doreen El Haddad [11:08]:
"These are really, really tiny changes that affect people in physics doing measurement, fundamental research. So, yeah, no one in the world would notice anything."

The Influence of Measurement Systems on Daily Life

Despite expert explanations, the issue persists as Alex discovers that the US customary system lacks the precision and standardization found in the metric system. Doreen suggests that poorly calibrated home scales might contribute to the discrepancies but acknowledges that this does not fully explain the wide variance Eva encounters.

Doreen El Haddad [12:17]:
"One possibility could be, like, the scales are not calibrated. If somebody has a kitchen scale, like, measured it. If the scale is not calibrated, the mass would be off."

Cultural Attachment to Measurement Systems

The conversation shifts towards the cultural reasons behind the US's resistance to adopting the metric system. Alex interviews James Vincent, a journalist and author of "Beyond Measure," who provides historical and cultural insights into why the US continues to use customary units.

James Vincent [18:53]:
"Measurement is a cultural practice. It says something about identity."

James explains that the US's attachment to its measurement system is deeply rooted in national identity and historical precedents, making the shift to metric both inconvenient and culturally significant.

James Vincent [20:18]:
"When America was founded... there was a lot of enthusiasm among the founding fathers for the metric system... but ultimately they had more important things to get on with."

Additionally, James highlights the lingering cultural discrepancies in the UK, where both metric and imperial units coexist, reinforcing the idea that measurement systems are intertwined with cultural identity.

James Vincent [22:11]:
"It's going to be, it's going to have a subtle French tinge to it that I can't explain. But the vibes are just off."

Conclusion: Seeking Practical Solutions

Returning to Eva, Alex acknowledges that despite extensive research, a perfect conversion from cups to grams remains elusive due to inherent system inaccuracies and cultural interpretations embedded in measurements. Ultimately, Alex and Eva agree on a consensus conversion of 227 grams per cup of butter, accepting it with the understanding that absolute precision is unattainable.

Eva Higginbotham [25:08]:
"I take it as a win. I'm gonna stick that number on my fridge."

Eva reflects on the broader implications of her problem, recognizing the necessity of reconciling with the imperfections of measurement systems while striving for practical solutions in her baking endeavors.

Key Takeaways

1. Measurement Systems: The US primarily uses volume-based measurements (cups), while the UK and most of the world use weight-based measurements (grams), leading to conversion challenges.
2. Standardization Issues: Historical efforts to standardize measurements, such as "Le Grand Coeur," have largely mitigated discrepancies, but minor variations still exist.
3. Cultural Significance: Measurement systems are deeply rooted in national identity and cultural practices, making transitions to standardized systems complex and often resisted.
4. Practical Solutions: Despite theoretical inconsistencies, practical conversions (e.g., 227 grams per cup of butter) provide workable solutions for everyday tasks like baking.

Notable Quotes

• Eva Higginbotham [02:48]:
  "Someone should have decided how much a cup of butter weighs."

• Alex Goldman [07:17]:
  "La Grand Coeur is to blame. Like, the gram isn't a constant thing."

• Nancy Silverton [15:12]:
  "A peanut butter cookie is a classic. What they call a rolled cookie... it needs to have round edges, and it needs to crack on top."

• James Vincent [20:27]:
  "Measurement is a cultural practice. It says something about identity."

Final Thoughts

"Eva Needs to Measure" is a compelling exploration of how something as mundane as measuring ingredients can unveil deeper issues related to standardization, cultural identity, and the intersection of science and daily life. Through Eva's baking challenges, the episode underscores the significance of measurement systems beyond their practical applications, highlighting their role in shaping and reflecting cultural identity.
