This is usually done by weighing. On Earth, mass and weight are proportional; in fact, balances are usually calibrated for mass units, even if some of them really determine the weight.
'Dry' volume - is measures in cubic centimetres... 'Wet' volume is measured in millitres.

3.5 units, or 3 units (to be pedantic).
If you have calibrated eyeballs
Insulin is measured in "units".
Calibrated spoons are used for pediatric patients; children. Because children's doses are small, they are ideal for administering small doses. Calibrated oral syringes (no needle) may also be ideal for administering small doses to children. Calibrated spoons may also be used in place of oral syringes for ease of use or patient preference; especially for the elderly.
Just about everthing
It is a measuring tape which is calibrated in metric units.

A 1cc/ml syringe allows you to measure in hundredths, while larger syringes will allow you to measure in tenths. cc - cubic centimeters ml - milliliters IU - international units (insulin syringes)
The volume is measured in L or submultiples.
Insulin is measured in units. 1ml is equal to 100 units. Lo-dose syringes are u-50 and u-30 particularly for children. U-100 is the standard for adults.

Do not use a TB syringe for your insulin. The standard these days is for insulin to be 100 units per mL, which would seem to measure the same, but the syringes are calibrated differently and they are not always equivalent. There's a high likelihood you'll take too much or too little, and this deficit or excess can really add up if you're taking insulin a few times per day. If you're not sure, take your insulin and your syringes to your doctor, a local urgent care, or maybe a pharmacy and get help from a professional; it's too easy to overdose or underdose if you don't understand your medication.
ISO 8537:2007 specifies requirements and test methods for sterile syringes, with or without needles, solely for the injection of insulin. The syringes are single-use only, primarily for use in humans. It covers syringes for use with 40 units of insulin/ml (U-40) and 100 units of insulin/ml (U-100). Sterile syringes specified in ISO 8537:2007 are intended for use soon after filling as they are not suitable for containing insulin over extended periods of time. ISO 7886-3:2005 specifies the properties and performance of sterile single-use hypodermic syringes with or without needle, made of plastic materials and stainless steel and intended for the aspiration of vaccines or for the injection of vaccines immediately after filling. Upon delivering a fixed dose of vaccine the syringe is automatically rendered unusable. ISO 7886-3:2005 does not specify the design of the auto-disable feature, which is left to the discretion of the manufacturer ISO 7886-3:2005 is not applicable to syringes for use with insulin (specified in ISO 8537), syringes made of glass (specified in ISO 595), syringes for use with power-driven syringe pumps (specified in ISO 7886-2), auto-disable syringes for variable dose delivery and syringes designed to be prefilled. It does not address compatibility with injection fluids/vaccines. Available from http://iso.org
