The arrow shows the average direction of the waves 1-2 miles out to sea. Lifeguards can give youĪdvice on waves if you’re planning to go into the water. One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. Period (more than 10 seconds) means the waves at the beach may be more powerful. The newton-metre (also newton metre or newton meter symbol Nm or N m) is the unit of torque (also called moment) in the International System of Units (SI). This is the average number of seconds between one wave and the next, 1-2 miles out to sea. Read more about calculating the expected height of the waves at the beach. Water, keep an eye on the waves to stop you or your belongings being swept away. Individual waves out to sea or at the beach can be higher than this number. This is the average height of the waves, 1-2 miles out to sea. 11 Extreme - Avoid being outside during midday hours. 8-10 Very high - Spend time in the shade between 11am and 3pm. 6-7 High - Seek shade during midday hours, cover up and wear sunscreen. 3-5 Moderate - Take care during midday hours and do not spend too much time in the sun unprotected.

If the arrow points from land to sea, the wind The arrow shows the direction of the wind (up is north). The number represents the average wind speed expected at that time. ![]() The letters show the direction the wind is blowing The arrow shows the direction the wind is blowing. Strong winds are shown in bold for speeds of 29 mph or more. Wind gust shows the highest wind speed that you should encounter at that time, as winds peak and Idea of how the temperature will actually feel at the time.

An avoirdupois pound is equal to 16 avoirdupois ounces and to exactly 7,000 grains.Ĭonversion calculator for all types of measurement units. In the United Kingdom, the use of the international pound was implemented in the Weights and Measures Act 1963. ![]() The definition of the international pound was agreed by the United States and countries of the Commonwealth of Nations in 1958. The international avoirdupois pound is equal to exactly 453.59237 grams. The most commonly used pound today is the international avoirdupois pound. The pound (abbreviation: lb) is a unit of mass or weight in a number of different systems, including English units, Imperial units, and United States customary units. It was first used around 1904, but not until 1948 was it officially adopted by the General Conference on Weights and Measures (CGPM) as the name for the mks unit of force. In physics, the newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton in recognition of his work on classical mechanics.
