Imperial vs Metric!

Why does the US persist with the Imperial system of measurement? It is archaic and extremely frustrating. The USA is one of only 3 countries left in the world where the Metric system has not officially been adopted; the other two are Myanmar (Burma) and Liberia!

I am constantly frustrated by the continued use of Imperial measurements in the USA. Whilst cooking the other day, a recipe called for a quart of water – I had to go and look it up – I had no idea (it’s just short of a litre, or almost 4 cups, by the way)! Using miles instead of kilometres is bad enough, but having to convert pounds and ounces, inches, feet, yards and miles and fluid ounces, quarts and gallons does my head in! Not to mention the use of Fahrenheit instead of degrees celsius – that is just annoying. Celsius is so much easier – water freezes at 0°C and boils at 100°C – simple! (For those curious, the respective values in Fahrenheit are 32°F & 212°F). But Americans are afraid of change (I’m hoping it’s not arrogance). So, let me reassure my Americans friends, there is nothing to fear – it’s easy – the Metric measurement system is all based on a factor of 10 – simple really!

The below image showed up on Facebook, so I’ve borrowed it from there to illustrate:

The metric system is used in the fields of medicine, science and technology and even in international sporting events like the Olympics (e.g. the running track is 400m). It is after-all, the International standard for measurement. So, when will the USA catch up to the rest of the world and switch to the International System of Units and embrace the metric system?

For those Americans who would like to know more I have added  simplified (I, hope) table to explain, otherwise –  here might be a good place to start.

Base units for each measurement type:
Length Metre (m)
Weight Gram (g)
Volume Litre (L)

What the prefixes mean:

Milli (m) 1/1000
Centi (c) 1/100
Deci (d) 1/10
Deca (da) x10
Hecto (h) x100
Kilo (k) x1000
* Deci, Deca & Hecto are not routinely used in everyday measurements

For weights and volumes generally only the base unit and the milli and kilo prefixes are routinely used in everyday measurements. For lengths – the additional use of centimetre (cm) is common. So, the most common examples would be:

Lengths: 1km = 1000m and 1m = 100cm = 1000mm

Weight: 1 kg = 1000g and 1g = 1000mg

Volume: 1L = 1000mL
