Source(s): Women wear headscarves tied at the front to prevent headaches from sky pushing down and to prevent throat cancer. Mega-tsunami for New York will be 400 meters; then engulfed-in-lava Los Angeles will be flooded too; also, asteroid destroys Gulf of Mexico; only Alaska, Eurasia, and Africa remain (obviously without coasts). 1st big earthquake in Russia; 2nd bigger one in China (will be split in half; radiation!); 3rd biggest will be in the USA (Greek Orthodox monk Elidiy from Africa); forgive me.

1 foot up or down for every 10 feet horizontal.

It refers to the gradient of the slope which you are driving up or down. It is advise that you should change you gears appropriately. It is only given on particularly steep slopes where changing gears is advised.

That'll be a 1 in 10 slope - 1 metre or yard up for every 10 metres or yards along. A 100% hill would be a 1 in 1, a 45 degree slope.

It means you go up vertically 1 metre for every 10 metres you travel horizontally.

Divide 100 by the percent to give 1 in X ie.

10% is 1 in 10,

12.5% is 1 in 8,

20% is 1 in 5,

It's a measure of the gradient. A 10% hill is also known as 1:10 or 1 in 10. For every ten metres of length, it rises one metre.

A 25% hill is 1:4 or 1 in 4, which is pretty steep but not the steepest you might meet in the UK. The steepest I have driven up was 33% or 1 in 3.

Look at it as if it is almost equivalent to Degrees.

45 Degrees was a rise of 1ft height in 1ft travelled (incredibly steep 1:1).

Anyway: see the chart
