**What do we mean when we say "1 kg of bananas"?**

## Homework Statement

If I buy 1 kg bananas in a supermarket on the moon, will I get the same amount (mass) of bananas as if I bought them on the earth?

## Homework Equations

w=mg

g moon = 1/6 g earth

## The Attempt at a Solution

It depends on what they mean by 1 kg surely. If the supermarkets are meaning 1 kg mass, the answer is yes. If they mean 1 kg wt (= force) then no. What does the supermarket mean when they say "1 kg"?

Another way of looking at it: If they us an oscillatory balance, yes. But, if they use a spring balance, no. Am I right?
