Looking at some material on ebay the size says 135x50 CM What would that be in inches ?

[fyrffytr1]

53.1496"s X 19.685"s

2.54 cm = 1 inch so 53" x 19.7"

This website is excellent for converting between metric and english units of length:

The main page offers conversions for everything. I often use it for pressure and torque conversions.

That's actually such a common inquiry, if you put '135cm' in a Google search, before you can even finish typing, it will offer '135cm to inches'. Same with just about any metric number.

Just ask Siri

I just memorize the number .0393 .. 1mm = .0393", 1 cm = .393" 10cm = 3.93" 100cm (1 metre) = 39.3" etc.

There's the countries that use the Metric system, and the one that went to the Moon.

Then there's British Wentworth.

Most calculators that come with a phone, tablet, computer etc. have a 'converter' settiing.

Contrary to urban myth, NASA did use the metric system for the Apollo Moon landings. SI units were used for arguably the most critical part of the missions – the calculations that were carried out by the Lunar Module’s onboard Apollo Guidance Computer (AGC) during the computer-controlled phases of the spacecraft’s descent to the surface of the Moon, and for the journey of the Ascent stage of the craft during its return to lunar orbit, where it would rendezvous with the Command and Service Module (CSM).

As is the case in the UK with road signage, the use of metric units in the USA is often hidden from public view. The Apollo Guidance Computer is a good example of this. The computer display readouts were in units of feet, feet per second, and nautical miles – units that the Apollo astronauts, who had mostly trained as US Air Force pilots, would have been accustomed to using. Internally, however, the computer’s software used SI units for all powered-flight navigation and guidance calculations, and values such as altitude and altitude rate were only converted to imperial units when they needed to be shown on the computer’s display.

and time was computed in Julian date.

Pretty much all of Science, the US Military, Medicine, NASA and Auto manufacturing employ the Metric system. That doesn't make me a proponent, though. My construction projects are invariably in Imperial from the drawing stage to building it out. Sometimes, if it's a Government project, then the drawings will be Metric. You have to be damn careful and not convert the numbers. There's a difference between a 3 foot wide office door and a 915mm door. Another Site Super that I know had to change over 100 shop finished doors due to that oversight.
Anyways, it's good to know both systems. For me anyways, as I have built stuff all over the world.

[Stuart]

That's interesting - I've worked on a half dozen or so construction projects in Canada in the last decade, and all were metric. Some were government projects but the others were private industry.

The Soviet Union, Japan, the European Space Agency, China, India, Luxembourg, and Israel have all had moon missions. All metric.

Do you really believe that the high level of intelligence required to send someone to the moon and back is based on which unit of measurement is used?

Besides that while the US separated itself from British rule, it retained their basic system of measurement, so you are still under British influence.

From the American National Standards Institute:

"Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s, it has been based on the metric system and defined as exactly 25.4 mm".

Decimals?? We don't need no steenking decimals!

53 1/8" x 19 11/16", or (my personal preference) roughly 4' 5" x 1' 8".
