How fast is .88 mach

The fact that everybody says, "Why 88 miles an hour? What's so special about that? That's all. There's no special significance to that. And there's also an interview here where he adds that aside from being memorable, another reason was that it was fast enough that the characters wouldn't accidentally go that fast when just driving the DeLorean around and not trying to escape Libyan terrorists :.

Two reasons. First of all we wanted it to be a speed that somebody wouldn't accidentally drive at. The other thing is, is it's easy to remember. Everybody remembers 88 miles an hour. Maybe you'd remember 89 miles an hour. I don't know, 88 just had the right ring to it. A driver of average competency begins to seriously increase the risk of crash when 20kph over the speed limit, as shown in this figure :. If they made it lower, it probably wouldn't have been cool enough to take effect.

But if they made it higher, they'd run the risk of people actually trying to do it. According to the Daily Telegraph :. Sign up to join this community. The best answers are voted up and rise to the top.

I'm guessing because the led display would seem more dramatic if all the lights were lit up and since 88 is the number that would do this, it was what was chosen.

Must be for the yards per second metric - I see 42 in there. OghmaOsiris - I think you can even take this explanation in-universe. Imagine that the speed is arbitrary - you fix it by changing variables in the machine Doc has to come up with an arbitrary large speed, and since he's using an LED display for the spedometer, he decides it would look cool. We know that Doc has a flair for the dramatic anyhow.

It's been repealed since , but some states including mine still have a 65 mph speed limit. Other states have higher or lower limits, but most aren't any higher than 80, so 88 would be considerably fast and faster than legal in , when a 55 MPH limit was the national law en.

The point is that it's , furlongs per fortnight. Show 7 more comments. Active Oldest Votes. As you can see here the original set of DeLoreans were fitted with speedometers that went up to 85 MpH: Further evidence on Wikipedia supports this. Improve this answer. Ry- 5 5 bronze badges. The end result should be a reasonably accurate estimate of your aircraft's airspeed potential. Use this process to help determine the amount of propeller pitch you need for your particular aircraft.

Use the Theoretical Speed Calculator below. Propeller Tip Speed Calculator. In inches. Calculated using outside temp. Maximum performance between 0.

A propeller does not work well just under and over Mach speed. Just under Mach 0. The link will appear on the page as: Speed units converter. For online collaboration to improve the Speed units converter Convert to units and culinary measures. Have a nice weekend …. Going for a boat trip this weekend and so I was just wondering how to convert knots feet per min or hr, mile per minute or hour mph and that sort of thing to learn more closely about the speeds and measures that seamen practice out there on the seas.

Basically, I was looking for how fast in mph to drive in it on the streets with speed limits in kms. The converting 2. All I have to remember is the 1 to 1 conversion below and with it always multiply km by the 0.

This is what I was finding out, changing driving speed from kilometers to miles in one hour time. Thank you for the calculator with all speed units available in it. Gives accurate and fast conversions which is very useful. With my walk-o-meter I measured that my natural walking speed or distance in exactly ten minutes is almost precisely one kilometer km or one thousand meters m.

I had a thought to convert this speed into yards and feet. Just my speed to time calculations if handy for other power walkers out there using a local map for park walks. Speed: 1 mile per hour mph , Equals: 0.
