Here are some great pages that can help you on your way:
There’s a wealth of instant info at www.onlineconversion.com Length, speed, temperature, acceleration, angles, currency, dates, times, density, energy, flow rates, length or distances, and light are just some of the conversion charts they feature. You’ll never have any more trouble with math problems after you bookmark this site.
Go to www.convert-me.com/en to get charts for capacity and volume, speed, temperature, time, pressure, fuel consumption, torque, and many others. The site is easy to navigate and everything is listed in categories that makes it easy to find the subject in which you’re interested.
If you’re in a particular line of work you may find this site helpful. They have hard conversions for construction materials, mass conversion factors, pavement conversion factors, power conversions, pressure or stress conversion, reinforcing steel conversion and so much more. Check it out at www.wsdot.wa.gov/reference/metrics/factors.htm
Here’s another site where people in particular trades can find helpful info: www.fisherregulators.com/technical/tables. They have charts or volume rate equivalents, pressure equivalents, kinematic-viscosity conversion formulas, gas volume conversion, and other technical formulas.
If you cook a lot, www.that’smyhome.com/conversion.htm is a place you’ll want to bookmark. Use their recipe conversion tables for dry measures, wet measures, spoon measures and more.
