I know that data, angles, and time are all measured the same way in both systems. Electrical measurements are only done in metric (except for the horsepower). Are there any other measurements that have the same units in both systems?
Measurements of radiation: Sieverts, curies, etc.
And while there are Imperial units for very small distances (millionths, billionths of inches) no one uses them. Everyone uses microns and nanometers. Similarly, for very large distances, everyone uses light years or parsecs, which are neither metric nor Imperial units.
You speak of “both systems”, but there’s really only one system here, and one hodgepodge. There isn’t any “official imperial unit” for angles, or electric potential, or a lot of other things, and there isn’t even a consistent standard for fundamentals like mass.
Also, you probably aren’t actually referring to the imperial system at all, which was only ever used by Britain, and hardly even that any more. America has never used the imperial system, just a close relative of it which might as well be called the American system for lack of any better name.
There is one. Minus 40 is the same on the Fahrenheit and Celsius temperature scale. Those scales proceed at a ratio of exactly 1.8:1 from -40.
The OP could be a Briton, in which case they probably do mean Imperial. At any rate, the only difference between Imperial and US Customary units is in volume measurements.
The OP is looking for units, not specific measurements.
I am American.
Yeah, but that’s equivalent to saying “0 inches is equal to 0 meters”.
Technically there are 2 metric systems (SI and cgs). I agree there is no such thing as a standard “Imperial” system.
The OP mentioned angles, but there are many different units for angles: radians, degrees (decimal), degree/arcminute/arcsecond, grad, etc. And I think radian is the standard for SI.
Fuck yeah.
No it isn’t because -40 is not zero, it’s an actual value which is not equal by definition, like zero… There are measurable temperatures above and below that which are not the same. It’s like saying 40 inches is the same as 40 meters, which is not what I’m saying.
Celsius isn’t really metric, unless the definition of metric is just ‘not what America does’
Three if you count MKS.
Zeroes aren’t equal by definition, either, though: If they were, then 0 Celsius would be equal to 0 Fahrenheit, which it’s not. Unless you want to argue that we shouldn’t be using scales with arbitrary zeros, in which case we shouldn’t be talking about Celsius or Fahrenheit at all, but Kelvin and Rankin.
Mk VII, SI is MKS. Though there is still some further variation in the details of how electromagnetic quantities are defined. And one could, I suppose, define other “metric systems”, such as the meter-ton-second system, which I’ve half-facetiously advocated for.
Both of the pre-algebra textbooks I’ve taught from call it just that: The American System of Measurement.
It’s usual name is US Customary units
all the measurements are the same. the units may be different.
There are a few cases where common metric units (or the metric units chosen to be used commonly) are similar to previously existing non-metric units.
For example, a metre is more or less the same as a yard - close enough that for everyday linear approximations, it’s often interchangeable.
A tonne is quite close to a ton.
This is how I have to offhand mm to inches in daily practice.
It’s not absolute, but close enough for estimates.
I see things in Half’s and Thousandths of an Inch.
25mm=1 inch
19mm=3/4*
12mm=1/2
8mm=5/16*
6mm=1/4
3mm=1/8
1mm=.040
.5mm=.020
.25mm=.010
.125mm=.005
.0625mm=.0025
.03125mm=.00125
.015625mm=.000625
.0078125mm=.0003125
*In these two places metric and Imperial measurements coincide, in no significant way, other than u can use the same socket wrench on them.
Also, One Thousandths of and inch is pretty close to a 32nd of a millimeter…Fascinating. :dubious:

Only if the ton is long (1016 kg). The short ton is significantly less (907 kg).
