I want to set the altitude on my suunto watch

grid refs are SE 37930 36412 (WGS84)

thanks

Ordnance Survey get a map and use the contour lines?

find your house on google earth, it should show the elevation

322ft

About 97m.

I know where you live!

99m

Whats that boozer like?

boozer poor but organic ale at £1.40/pint is ok

do you have a Garmin device of any variety?

i do but i am not sure how accurately it has been caliberated

go to a beach, set it to zero.

Type your postcode into the following ordnance survey site and zoom in on the map until you can read the contour lines….

Google Earth is your best bet.

If you use a barometric altimeter you can get the local pressure setting from a nearby airport. Remember that at your elevation and considering the colder weather you might want to subtract about 20 feet.

Dont use a sat nav. My phone came with Copilot installed and it claims that bournemouth prom is 110 feet above sea level

you’ll need to get used to checking the height of a point on an OS map and resetting as the weather changes, since pressure altimeters rely on a datum being accurately set. not that often, but certainly from day to day if you’re going to use it to aid your nav.

surface pressure (QNH) can vary widely: typically 970mb to 1030mb at sea level are not uncommon, with 1013 being a standard day. each mb makes 30ft of difference

QNH is sea level pressure, QFE is surface pressure.
I’ve seen pressure changes 4 times in an hour (that works out at 120ft) so you need to change it more than just daily if you want to accurately measure altitude.

QNH isn’t sea level pressure, it’s the QFE mathematically corrected to sea level assuming standard conditions. QNF is the QFE mathematically reduced using actual conditions.

Flaperon, QSY off to pprune, where people may care.

As above – you’ll need to constantly reset the altitude. On a typical days spring or autumn walking in the Scottish Highlands, I’ve had to do this up to 6 times. However, if you know you’re altitude and it changes while you’re stationary (e.g. overnight) this can help identify incoming weather.

Look on an OS map and see if there is a BM (Bench Mark) near you?

I used Google Earth and found I am at 197 m (646 ft). Who lives the highest?

Or an earthquake…

Spesh99 – are you my neighbour?

Spesh99 – are you my neighbour?

Don’t think so I’m in Balerno in Edinburgh. I almost live in the Pentland Hills.

I’ve just checked and my house starts at ground level and goes up about 30ft.

Gulp! Where in Balerno?

Why where are you? Click my name and email me if you wanna know where I am.

Who lives the highest?

I live in Holland so I’m willing to bet it’s not me.
