Metrication is a great help but has also created anomalies I have seen pressure gauges changed from a commonly used psi to kg/cm.sq., bar, pascal, kPa and atmos but will no doubt Go back to first principals and double check your calculations if the result is 'mission critical'. We have tried to be accurate with the data but cannot be held responsible for inaccuracies. If accuracy is critical beware of old versions of MS Excel which Scientific notation - 1.76 E+09 or 3.78 E-12Ĭuts out a lot of noughts. The upper case L for liter is preferable as the lower case canīe confused with the figure one, however it is common to see Remember that 1 Litre of pure water weighs 1Įqually, 1 milliliter of pure water has a mass of 1 gram or Grams in the same way as a kilometer is 1,000 metres. the prefix 'kilo' means '1,000' so a kilogram is in fact 1,000 You won't usually find a conversion from kilograms to grams Many horsepower in a 500cc engine which is an impossibleĬonversion but I have given an approximation on this Units must remain the same - mass converted to mass, lengthĬonverted to length, and so on. You will not find a conversion from pounds to metres - the basic Remember that you cannot create energy only convert it. Episode 1: Desperate Measures! The SI Superheroes use the power of measurement to help a stranded soccer player get home.From the tables: 1 acre = 160 sq.rods, soįeet, inches and fractions of an inch to metric and from.Episode 2: Running Out of Time! The SI Superheroes battle archvillain Major Uncertainty in a race to keep the world's satellite navigation system "on time.".Episode 3: Mass Hysteria! The nefarious Major Uncertainty has kidnapped Monsieur Kilogram, putting the world’s measurements of mass in jeopardy.After rescuing Monsieur Kilogram and capturing Major Uncertainty, our Superheroes take a break and play a game of "Two Truths & a Lie." Comic book-style video animations, available on the NIST YouTube Channel. Contact the NIST Metric Program at TheSI and include your name and U.S. Hardcopy charts are available while supplies last. Additionally, mention the combination of SI base units creates the SI derived units. Use this Conversion Calculator to convert between commonly used units. State each base unit depends upon a defining constant. Teaching TipsĮxplain the SI base units, unit definitions, and metric prefixes. Use caution when handling paper edges to prevent injury. Recognize the definitions of base units (Opens a modal) Metric units of mass review (g and kg) (Opens a modal) Metric units of length review (mm, cm, m, & km) (Opens a modal) Metric units of volume review (L and mL) (Opens a modal) U.S.Example 2: Convert 500 millimeters to feet: 500 mm x 0.03937 19.7 inches, and there are 12 inches in. Example 1: Convert 500 millimeters to inches: 500 mm x 0.03937 19.7 inches. The chart may be printed on any paper size but is recommended to be at minimum 215.9 mm x 279.4 mm (8.5 in x 11 in). If you need to convert from Imperial or US Standard units to Metric, or the other way around, one of the tables below should help. NOTE: Four new International System of Units (SI) prefixes (ronna, ronto, quetta, and quecto) were adopted in November 2022 and are not currently represented in this publication. The chart provides an entertaining way to learn more about the International System of Units (SI).
SI Prefix symbols featured in the chart are used to represent smaller or larger units by factors that are powers of 10. The superheroes include the following: Mole, Professor Second, Monsieur Kilogram, Ms. This resource provides a colorful printable SI system chart, which displays the 7 SI base unit, prefix symbols, and features the Measurement League: Guardians of the SI superheroes, dedicated to the fight against uncertainty, imprecision, and inaccuracy and to improving the quality of our lives and the things we build.
