I second this! I was in the US for a while and quickly realised that doing constant conversions was a PITA, so I learned some rough reference points in imperial.
I think it’s good to get some small and some large reference points, which make it easy to guesstimate other things based on what you know. Mine were (given in metric here):
- A glass of beer is 0.5 L.
- A big barrel is about 200L (0.2 m^3).
- My walk to work is 3 km, a long hike is 25 km.
- A very short person is about 150 cm, a very tall one is about 2 m.
- I can deadlift about 100 kg, and bicep curl around 15 kg.
- A potato is on the order of 100g, while a watermelon is around 2kg.
- 70 C is a nice sauna, 25 C is a nice summer day, 10 C is chilly, 0 C is sleet-temperature, -10 C is powder snow cold (depending on where you live the colder temps might be more or less relevant)
Figure out some similar things for yourself, and it’ll be relatively easy to think along lines like “That walk was a bit further than my way to work, so it’s probably about 4km”, or “that box was heavy, but far from 100 kg, so it’s maybe around 30 kg.”
Bonus points if you try some guessing like that and double check afterwards to tune in your feeling for different measurements.
Exactly! I’m sick of people being labelled as racist because they’ve said some keyword that someone has decided makes them racist, even when their intents and opinions are clearly not racist.
Saying it’s “uncivilised” to publicly beat someone to death because they <insert whatever>, cannot be racist, because you’re not concerned with “race” in any way. Going further and saying that a country that allows such practices is uncivilised is, again, inherently not racist, because the reason for calling them uncivilised has nothing to do with the “race” of the people involved.
