Working with metrics is much easier, because you work with what I
call a 10-system.
1 meter = 10 decimeter=100 centimeter= 1000 millimeter.
With imperial it's much more complicated.
1 yard = 3 feet = 36 inches
And then you divide the inches in half, quarters, eights and
So 1 yard = 72 x 1/2" or 144 x 1/4" or 288 x 1/8" or 576 x 1/16"
And it becomes really complicated when you have to multiply or
divide measurements as 2 3/4" or 11 5/16"
So for me metric is the most logical and efficient way to measure.

I know that using inches is "easier" if you have not gotten
involved with using metric measurements - but I'd like to
suggest not making the change and leaving your measurements as
metric so you can learn and have an easier time in the future.
Here's why-- If you are having to move designs around,
re-center them, enlarge/reduce size etc... If you are using
inch measurements - it's harder to determine what 1/2 would be
if you are using 7/8" or 3/8" or 1-5/8" etc. These types of
measurements are harder to cut in half and then you end up with
8ths, 16ths, 32ndths of an inch etc. But- if you are using
metric and remember that 1in = 25mm, 1/2in = 12.5mm, 1/4in =
6mm, 1/8in = 3mm those 4 are the basis for being able to do most
calculations using metrics. They are the ones you would use the
most with quilting and embroidery. And once you start doing it
pretty often, it comes naturally. So- 7/8in = 21-21.5mm and I
typically drop that .5mm because it's really *so* small. (I
added 12.5 + 6 + 3 = 21.5mm). And- if it's a problem for you -
you can make a chart and keep it handy so it's even easier.
But- here's the big thought... It's much easier to find the
center of something that measures 21mm than it is 7/8" since you
only cut 21 in half and come up with 10.5 (I round it to 10) so
you can move something 10mm easier than you can stop to figure
out what half of 7/8in is and then it's going to be off more
when/if you round the # you get. And- if you are like me, when
I was doing inches... I would have to have a tape measure and
then use it to determine where half would be. Where's the tape
measure when you need it?? To move a design 3/4in to the left
(example) you would move it 18mm (1/2=12, 1/4=6mm).
Most digitizers use metrics for design sizes. Some will list
them with both measurements because they never know who might be
buying their designs and don't want anyone to have to do the
math (altho it's not hard for many....) Most hoop sizes are
listed in metric measurements so you can start from there. If
your hoop is 200x200 then you know center is 100mm going from
the notches on each side of your hoop. That's 4inches since you
know that 25mm = 1in and 100mm divided by 25 is going to be 4.
But if your hoop is 5.5in x 7.9in (like one of mine) .... it's
harder to figure out where center is by cutting those numbers in
half than if you use 140mm x 197mm. Cut both of the latter #s
in half. Newer Janome larger hoops that are 9.1in x 11in
convert to 227mm x 275mm (the 12000, 15000, 14000 models
machines) or the 550e has the 7.9 x 14in which converts to 197 x
Obviously, it's your choice. This is just something to think
about and my opinion... If you are moving designs around to
group them, ungroup then center etc.... Metric makes it easier.
I really wish we had all grown up doing the metric system. I
didn't but have converted most of my measurements since becoming
a nurse 40yrs ago, quilter 30yrs ago, and machine embroiderer
