What is it?
A 401(k) in-plan Roth conversion (also called an "in-plan Roth rollover") allows you to transfer the non-Roth portion of your 401(k) account into a designated Roth account within the same plan. The amount you convert is subject to federal income tax in the year of the conversion (except for any nontaxable basis you have in the amount transferred), but qualified distributions from the Roth account in the future are entirely income tax free. The 10% early distribution penalty doesn't apply to amounts you convert (but that tax may be reclaimed by the IRS if you take a nonqualified distribution from your Roth account within five years of the conversion).

What part of my account can I convert?
Here's where it gets a bit tricky. Assuming your 401(k) allows in-plan conversions (plans aren't required to), you have to be entitled to a distribution from the plan in order to make a conversion. For example, you're generally entitled to a distribution from your 401(k) plan after you terminate employment. If your account balance is greater than $5,000, you also have the right to keep your money in the plan until you reach normal retirement age (typically 65). So in this case, your plan may allow you to transfer all or part of your account into a Roth account (except for any required distributions and certain periodic payments).
But what if you're still employed? If you want to transfer your pretax contributions and earnings into a Roth account, you'll generally only be able to do so if you're age 59½ or disabled, or you've received a qualified reservist distribution, because those are the only events that can trigger an eligible distribution (hardship withdrawals aren't eligible for rollover or conversion). In some cases, your vested employer contributions (and earnings) may also be available for distribution while you're still employed--for example, after the contribution has been in the plan for two years, or after you have 60 months of participation (the terms of your plan, and federal law, control). If your plan allows these distributions, it can also allow them to be converted.
Keep in mind that if you're entitled to an eligible rollover distribution, you can always roll those dollars into a Roth IRA instead of using an in-plan conversion.
Some employers aren't comfortable letting employees withdraw their retirement funds while they're still employed. The IRS has addressed this concern by letting 401(k) plans provide for the in-service distributions described above only if the employee intends to convert those funds. For example, a plan that currently doesn't let employees withdraw pretax dollars at age 59½ can be amended to allow those withdrawals, but only if an employee intends to roll those dollars into a Roth account--the employee would not be allowed to actually take a distribution of the funds, or roll the dollars over into an IRA.
What else do I need to know?

If you have the choice of an in-plan conversion or a rollover to a Roth IRA, which should you choose? There are a number of factors to consider:
- You can recharacterize (undo) a Roth IRA conversion if the conversion turns sour (for example, the value of the converted assets declines significantly), but you can't recharacterize in-plan conversions.
- In general, the investments available in an employer 401(k) plan are fairly limited, while virtually any type of investment is available in an IRA (on the other hand, your 401(k) plan may offer investments that you can't replicate in an IRA, or that aren't available at similar cost).
- Finally, 401(k) plans typically enjoy more protection from creditors under federal law than do IRAs (consult a professional if creditor protection is important to you).
