The high price of a bad translation

Words carry weight. In business, a single mistranslated word can change the meaning of a contract, shift how a brand is perceived or even cause multi-million losses. Throughout history, companies, governments and institutions have made translation mistakes with devastating consequences.

From pharmaceuticals to finance and global marketing, the importance of professional translation becomes obvious when you look at real cases of errors that cost fortunes. In this article we look at some of the costliest translation mistakes in history, their consequences and the lessons we can draw so that your company does not repeat them.

Translation mistakes that cost millions

A bad translation that destroyed the Mars Climate Orbiter

One of the biggest translation mistakes in scientific history happened in 1999 at NASA. The Mars Climate Orbiter, a probe designed to study Mars, was destroyed because of a unit conversion failure.

• The team at Lockheed Martin, responsible for navigation, used imperial units (inches and pounds) in its calculations.
• The team at NASA, on the other hand, used metric units (metres and kilograms).
• As a result, the probe entered the Martian atmosphere at the wrong altitude and disintegrated, causing losses of 327 million dollars.

This case shows how a simple translation error between systems of measurement can have catastrophic consequences.

🔹 Lesson learnt: always check the accuracy of technical and scientific terminology with language experts who specialise in the field.

Coca-Cola’s costly mistake in China

When Coca-Cola tried to enter the Chinese market, one of its first attempts to transliterate its name produced an unfortunate reading:

• the initial rendering of “Coca-Cola” in Chinese was “Ke-Kou-Ke-La”, which in some dialects meant “bite the wax tadpole”.
• Clearly, this was not the most suitable translation for a soft drinks brand.
• The company had to redo its entire advertising campaign, at a cost of millions of dollars in rebranding and product adaptation.

🔹 Lesson learnt: literal translations do not always work. It is essential to work with brand localisation specialists so that the message fits each culture.

HSBC and its unfortunate campaign slogan

HSBC spent 10 million dollars relaunching its global slogan after a glaring translation error.

• Its original English slogan, “Assume nothing”, was mistranslated in several countries as “Do nothing”.
• This confused customers and damaged trust in the brand.
• HSBC had to redesign its slogan as “The world’s private bank”, spending a fortune on the new branding strategy.

🔹 Lesson learnt: in marketing, every word counts. An error in the translation of corporate messages can change how customers see you.

The translation error that almost caused a nuclear conflict

In 1945, during the Second World War, a translation error almost triggered an international crisis.

• The Japanese government used the word “mokusatsu” in response to the Allied surrender demand.
• The term can mean either “to take into consideration” or “to dismiss with silence”, depending on the context.
• The misreading of the message led the Allies to believe that Japan was rejecting surrender, which hastened the decision to drop the atomic bombs on Hiroshima and Nagasaki.

🔹 Lesson learnt: in diplomacy and international politics, an accurate translation that respects context is crucial to avoid catastrophic misunderstandings.

The medicine that caused birth defects because of a translation error

In the 1950s, thalidomide was introduced as a drug to treat nausea in pregnant women. However, a translation error in the medical documentation meant that its use spread without clear warnings about the side effects.

• The German term “nicht teratogen” was misread as “not dangerous for pregnant women”, when it actually meant “not tested on pregnant women”.
• As a result, more than 10,000 babies were born with congenital malformations.
• This disaster cost billions in lawsuits and changed the regulation of medicines worldwide.

🔹 Lesson learnt: in medical and pharmaceutical translation, accuracy and expert review are fundamental if tragedies are to be avoided.
